Dual Roles of Fer Kinase Are Required for Proper Hematopoiesis and Vascular Endothelium Organization during Zebrafish Development. BIOLOGY 2017; 6:biology6040040. [PMID: 29168762 PMCID: PMC5745445 DOI: 10.3390/biology6040040] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/15/2017] [Revised: 11/17/2017] [Accepted: 11/18/2017] [Indexed: 11/17/2022]
Abstract
Fer kinase, a protein involved in the regulation of cell-cell adhesion and proliferation, has been shown to be required during invertebrate development and has been implicated in leukemia, gastric cancer, and liver cancer. However, in vivo roles for Fer during vertebrate development have remained elusive. In this study, we bridge the gap between the invertebrate and vertebrate realms by showing that Fer kinase is required during zebrafish embryogenesis for normal hematopoiesis and vascular organization with distinct kinase dependent and independent functions. In situ hybridization, quantitative PCR and fluorescence activated cell sorting (FACS) analyses revealed an increase in both erythrocyte numbers and gene expression patterns as well as a decrease in the organization of vasculature endothelial cells. Furthermore, rescue experiments have shown that the regulation of hematopoietic proliferation is dependent on Fer kinase activity, while vascular organizing events only require Fer in a kinase-independent manner. Our data suggest a model in which separate kinase dependent and independent functions of Fer act in conjunction with Notch activity in a divergent manner for hematopoietic determination and vascular tissue organization.

Abstract
Noonan syndrome (NS) and LEOPARD syndrome (LS) cause congenital afflictions such as short stature, hypertelorism and heart defects. More than 50% of NS and almost all of LS cases are caused by activating and inactivating mutations of the phosphatase Shp2, respectively. How these biochemically opposing mutations lead to similar clinical outcomes is not clear. Using zebrafish models of NS and LS and mass spectrometry-based phosphotyrosine proteomics, we identified a down-regulated peptide of Fer kinase in both NS and LS. Further investigation showed a role for Fer during development, where morpholino-based knockdown caused craniofacial defects, heart edema and short stature. During gastrulation, loss of Fer caused convergence and extension defects without affecting cell fate. Moreover, Fer knockdown cooperated with NS and LS, but not wild type Shp2 to induce developmental defects, suggesting a role for Fer in the pathogenesis of both NS and LS.

Abstract
The control of microtubule and actin-mediated events that direct the physical arrangement and separation of chromosomes during meiosis is critical since failure to maintain chromosome organization can lead to germ cell aneuploidy. Our previous studies demonstrated a role for FYN tyrosine kinase in chromosome and spindle organization and in cortical polarity of the mature mammalian oocyte. In addition to Fyn, mammalian oocytes express the protein tyrosine kinase Fer at high levels relative to other tissues. The objective of the present study was to determine the function of this kinase in the oocyte. Feline encephalitis virus (FES)-related kinase (FER) protein was uniformly distributed in the ooplasm of small oocytes, but became concentrated in the germinal vesicle (GV) during oocyte growth. After germinal vesicle breakdown (GVBD), FER associated with the metaphase-I (MI) and metaphase-II (MII) spindles. Suppression of Fer expression by siRNA knockdown in GV stage oocytes did not prevent activation of cyclin dependent kinase 1 activity or chromosome condensation during in vitro maturation, but did arrest oocytes prior to GVBD or during MI. The resultant phenotype displayed condensed chromosomes trapped in the GV, or condensed chromosomes poorly arranged in a metaphase plate but with an underdeveloped spindle microtubule structure or chromosomes compacted into a tight sphere. The results demonstrate that FER kinase plays a critical role in oocyte meiotic spindle microtubule dynamics and may have an additional function in GVBD.

Abstract
Fes/Fer non-receptor tyrosine kinases regulate cell adhesion and cytoskeletal reorganisation through the modification of adherens junctions. Unregulated Fes/Fer kinase activity has been shown to lead to tumours in vivo. Here, we show that Drosophila Fer localises to adherens junctions in the dorsal epidermis and regulates a major morphological event, dorsal closure. Mutations in Src42A cause defects in dorsal closure similar to those seen in dfer mutant embryos. Furthermore, Src42A mutations enhance the dfer mutant phenotype, suggesting that Src42A and DFer act in the same cellular process. We show that DFer is required for the formation of the actin cable in leading edge cells and for normal rates of dorsal closure. We have isolated a gain-of-function mutation in dfer (dfergof) that expresses an N-terminally fused form of the protein, similar to oncogenic forms of vertebrate Fer. dfergof blocks dorsal closure and causes axon misrouting. We find that in dfer loss-of-function mutants beta-catenin is hypophosphorylated, whereas in dfergof beta-catenin is hyperphosphorylated. Phosphorylated beta-catenin is removed from adherens junctions and degraded, thus implicating DFer in the regulation of adherens junctions.

Abstract
Protein tyrosine phosphorylation plays an important role in cell growth, development and oncogenesis. No classical protein tyrosine kinase has hitherto been cloned from plants. Does protein tyrosine kinase exist in plants? To address this, we have performed a genomic survey of protein tyrosine kinase motifs in plants using the delineated tyrosine phosphorylation motifs from the animal system. The Arabidopsis thaliana genome encodes 57 different protein kinases that have tyrosine kinase motifs. Animal non-receptor tyrosine kinases, SRC, ABL, LYN, FES, SEK, KIN and RAS have structural relationship with putative plant tyrosine kinases. In an extended analysis, animal receptor and non-receptor kinases, Raf and Ras kinases, mixed lineage kinases and plant serine/threonine/tyrosine (STY) protein kinases, form a well-supported group sharing a common origin within the superfamily of STY kinases. We report that plants lack bona fide tyrosine kinases, which raise an intriguing possibility that tyrosine phosphorylation is carried out by dual-specificity STY protein kinases in plants. The distribution pattern of STY protein kinase families on Arabidopsis chromosomes indicates that this gene family is partly a consequence of duplication and reshuffling of the Arabidopsis genome and of the generation of tandem repeats. Genome-wide analysis is supported by the functional expression and characterization of At2g24360 and phosphoproteomics of Arabidopsis. Evidence for tyrosine phosphorylated proteins is provided by alkaline hydrolysis, anti-phosphotyrosine immunoblotting, phosphoamino acid analysis and peptide mass fingerprinting. These results report the first comprehensive survey of genome-wide and tyrosine phosphoproteome analysis of plant STY protein kinases.

Abstract
Morphogenesis requires coordination of cell surface activity and cytoskeletal architecture. During the initial stage of morphogenesis in Caenorhabditis elegans, the concerted movement of surface epithelial cells results in enclosure of the embryo by the epidermis. We report that Fer-related kinase-1 (FRK-1), an ortholog of the mammalian non-receptor tyrosine kinase Fer, is necessary for embryonic enclosure and morphogenesis in C. elegans. Expression of FRK-1 in epidermal cells is sufficient to rescue a chromosomal deficiency that removes the frk-1locus, demonstrating its autonomous requirement in the epidermis. The essential function of FRK-1 is independent of its kinase domain, suggesting a non-enzymatic role in morphogenesis. Localization of FRK-1 to the plasma membrane requires β-catenin, but not cadherin or α-catenin, and muscle-expressed β-integrin is non-autonomously required for this localization; in the absence of these components FRK-1 becomes nuclear. Mouse FerT rescues the morphogenetic defects of frk-1 mutants and expression of FRK-1 in mammalian cells results in loss of adhesion, implying a conserved function for FRK-1/FerT in cell adhesion and morphogenesis. Thus,FRK-1 performs a kinase-independent function in differentiation and morphogenesis of the C. elegans epidermis during embryogenesis.

Abstract
Developmental analysis of the tyrosine protein phosphorylation levels in larval integument and partial characterization of the endogenous protein tyrosine kinase activity (PTK) in Ceratitis capitata are described in this study. Larval integument contains high levels of PTK activity at the early stages of the third instar, which progressively declines to low levels in the white pupal stage. An integumental 90-kDa polypeptide was identified to have prominent endogenous PTK activity and follow a similar developmental pattern. The major integumental phosphotyrosine-containing polypeptides have apparent molecular weights of 30, 41, 44, 46, and 54 kDa, respectively. Polypeptides with molecular weights of 62 and 73 kDa were identified as Ser/Thr-containing phosphoproteins and were shown to exhibit high levels of phosphorylation at the middle stage of larval development. These differences are likely to be due to the higher activation state of the protein tyrosine kinase(s) at the early stages of larval development.

Abstract
In search of ancient versions of phylogenetically conserved genes/proteins, which are typical for multicellular animals, we have decided to analyse marine sponges (Porifera), the most ancient and most primitive metazoan organisms. We report here the complete nucleotide sequence of Sycon raphanus cDNA coding for a 879 aa long protein, which displays high overall similarity in primary structure and organization of domains with non-receptor tyrosine kinases (TKs) from the Fes/FER family. The encoded protein, which we named Fes/FER_SR, has a highly conserved, 260 aa long tyrosine kinase domain at the C-terminus. Amino-terminal to the catalytic domain is an 85 aa long SH2 domain. The N-terminus is over 500 aa long and displays homology only with N-terminal domains of protein-tyrosine kinases (PTKs) from the Fes/FER family. Mammalian Fes/FER proteins show around 58% overall homology with Fes/FER_SR (identity and similarity) and lower homology was found with Drosophila melanogaster Fps (FER) protein (49%). Homologies in TK, SH2 and N-terminal domains are on average 78%, 65% and 49%, respectively. Fes/FER_SR shows next to best homology with the Abl family of non-receptor PTKs, while Src-related PTKs from the fresh-water sponge Spongilla lacustris are related only distantly to Fes/FER_SR. Phylogenetic analysis shows that the S. raphanus TK is indeed the most ancient known member of the Fes/FER family of non-receptor PTKs. The role of these PTKs in signal transduction in higher animals is still enigmatic; they are present in the nucleus as well as in the cytoplasm and FER is found in all cell types examined. The function of Fes/FER_SR in sponge, the most primitive multicellular animal which lacks specialized organ systems, remains to be elucidated.

Abstract
The study of oncogenes has provided numerous insights, not only into the mechanisms by which growth regulation becomes uncontrolled in cancer cells, but also into signal transduction processes which regulate the orderly proliferation and maturation of cells. c-fes/fps is a cellular oncogene which has been transduced frequently by mammalian and avian retroviruses. There are several features about Fes which suggest it may play a unique role in myeloid cell growth and differentiation. While it contains a tyrosine kinase and SH2 domain, there is no SH3 domain or carboxy terminal regulatory phosphotyrosine such as found in the Src family of kinases. Fes has a unique N-terminal domain of over 400 amino acids of unknown function. It has been implicated in signaling by a variety of hematopoietic growth factors, and is predominantly a nuclear protein.

Abstract
We used in situ hybridization to study expression of the DER gene during Drosophila development. DER encodes a transmembrane cell-surface receptor with a cytoplasmic protein-tyrosine kinase domain, and resembles the vertebrate genes that encode the EGF receptor and the neu protein. We examined most stages of development in the Drosophila life cycle and found a substantial correlation between DER expression and the phenotypes associated with a variety of mutant alleles. Of particular note were high levels of expression in the primordia of the mouth parts, which are the embryonic tissues most sensitive to reductions in DER activity; discrete expression in a subset of neural cells essential for construction of the axonal scaffold, a structure that is deformed in mutant embryos; uneven expression in the eye disc, the development of which is abnormal in both mild hypomorphs and hypermorphs; and expression in the follicular epithelial cells of the ovary, which are responsible for producing the eggshell of developing oocytes and do so aberrantly in the mildest hypomorphs. However, DER transcripts were also detected in a subset of tissues that have not been reported to be abnormal in mutant organisms. Our findings agree with and extend recently reported results for the DER protein, indicating that DER is regulated primarily at the level of transcription, in contrast to previous suggestions. We conclude that the phenotypes displayed by recessive mutants can be attributed to loss of DER function in the affected tissues.
