Abstract
In this study, the N-glycosylated protein profiles of cattle-yak longissimus thoracis (CYLT) and yak longissimus thoracis (YLT) were comparatively analyzed using quantitative proteomics techniques. A total of 76 differential N-glycosylated proteins (DGPs) were screened from 181 quantified N-glycoproteins, indicating that differences in N-glycosylation levels are key to the differences between CYLT and YLT. In particular, a variety of N-glycoproteins involved in the extracellular matrix were differentially N-glycosylated between CYLT and YLT, mainly including fibrillin-1, fibromodulin, collagen, and laminins. In addition, the N-glycosylation levels of several lysosomal-related proteolytic enzymes (cathepsin D, dipeptidyl peptidase 1, legumain, and aminopeptidases, etc.) were significantly higher in CYLT. These results indicated that the N-glycosylation of CYLT and YLT proteins plays a crucial role in the regulation of extracellular matrix organization (muscle fiber structure) and lysosomal activity (postmortem meat tenderness). The results remind us that posttranslation modifications, especially N-glycosylation, are still icebergs beneath the surface.

A Novel Legumain-Like Protease in Macrobrachium nipponense: Identification, Characterization, and Function Analysis in Ovary Maturation. Front Endocrinol (Lausanne) 2022; 13:858726.

Abstract
Legumain, also called aspartic endopeptidase (AEP), is a member of the cysteine protease family and is involved in various physiological processes. In this study, we analyzed the characteristics of a novel legumain-like (named Mn-Lel) in the female oriental river prawn, Macrobrachium nipponense, which is involved in ovary maturation. The Mn-Lel is 1,454 bp in length, including a 1,290-bp open reading frame that encodes 430 amino acids. qPCR analysis indicated that Mn-Lel is specifically highly expressed in the hepatopancreas and ovaries of female prawns. It is rarely expressed in embryogenesis, weakly expressed in early larval development stages, and then significantly increased after metamorphosis, which indicated that Mn-Lel is not a maternal gene and mainly plays a role in adults. During the different ovarian stages, Mn-Lel expression in the hepatopancreas had no obvious rules, while its expression in the ovaries had a significant peak in stage III. In situ hybridization studies revealed that Mn-Lel is localized in the oocyte of the ovary. Changes in the gonadosomatic index confirmed the inhibitory effects of Mn-Lel dsRNA on ovary maturation. These results suggest that Mn-Lel has a key role in promoting ovary maturation.

Abstract
The carnivorous whelk Rapana venosa is regarded as a biological invader with strong ecological fitness in the United States, Argentina, France and other countries. R. venosa may seriously damage bivalve resources. Nonetheless, in China, R. venosa is an important commercial species. Larval development, especially metamorphosis, influences the natural population and industrial breeding. However, there are few studies on the early development of R. venosa, and our understanding is further limited by a lack of genomic information. In this study, de novo sequencing was performed to obtain a comprehensive transcriptome profile during early development. A Hi-seq 2500 sequencing run produced 148,737,902 raw reads that were assembled into 1,137,556 unigenes (average length of 619 nucleotides, of which 49,673 could be annotated). The unigenes were assigned to biological processes and functions after annotation in Gene Ontology, eukaryotic Ortholog Groups and Kyoto Encyclopedia of Genes and Genomes. We also identified 93,196 simple sequence repeats among the unigenes. Six unique sequences associated with neuroendocrine function were analyzed by quantitative real-time PCR. Our data represent the first comprehensive transcriptomic resource for R. venosa. Functional annotation of the unigenes involved in various biological processes could stimulate research on the mechanisms of early development in this species. Understanding the mechanism of early development and metamorphosis would benefit antifouling research and aquaculture of R. venosa.

Structure and function of legumain in health and disease. Biochimie 2015; 122:126-50.

Abstract
The last years have seen a steady increase in our understanding of legumain biology that is driven from two largely uncoupled research arenas, the mammalian and the plant legumain field. Research on legumain, which is also referred to as asparaginyl endopeptidase (AEP) or vacuolar processing enzyme (VPE), is slivered, however. Here we summarise recent important findings and put them into a common perspective. Legumain is usually associated with its cysteine endopeptidase activity in lysosomes where it contributes to antigen processing for class II MHC presentation. However, newly recognized functions disperse previously assumed boundaries with respect to their cellular compartmentalisation and enzymatic activities. Legumain is also found extracellularly and even translocates to the cytosol and the nucleus, with seemingly incompatible pH and redox potential. These different milieus translate into changes of legumain's molecular properties, including its (auto-)activation, conformational stability and enzymatic functions. Contrasting its endopeptidase activity, legumain can develop a carboxypeptidase activity which remains stable at neutral pH. Moreover, legumain features a peptide ligase activity, with intriguing mechanistic peculiarities in plant and human isoforms. In pathological settings, such as cancer or Alzheimer's disease, the proper association of legumain activities with the corresponding cellular compartments is breached. Legumain's increasingly recognized physiological and pathological roles also indicate future research opportunities in this vibrant field.

Abstract
Scorpions are among the oldest terrestrial arthropods and they have passed through small morphological changes during their evolutionary history on land. They are efficient predators capable of capturing and consuming large preys and due to envenomation these animals can become a human health challenge. Understanding the physiology of scorpions can not only lead to evolutionary insights but also is a crucial step in the development of control strategies. However, the digestive process in scorpions has been scarcely studied. In this work, we describe the combinatory use of next generation sequencing, proteomic analysis and biochemical assays in order to investigate the digestive process in the yellow scorpion Tityus serrulatus, mainly focusing in the initial protein digestion. The transcriptome generated database allowed the quantitative identification by mass spectrometry of different enzymes and proteins involved in digestion. All the results suggested that cysteine cathepsins play an important role in protein digestion. Two digestive cysteine cathepsins were isolated and characterized presenting acidic characteristics (pH optima and stability), zymogen conversion to the mature form after acidic activation and a cross-class inhibition by pepstatin. A more elucidative picture of the molecular mechanism of digestion in a scorpion was proposed based on our results from Tityus serrulatus. The midgut and midgut glands (MMG) are composed by secretory and digestive cells. In fasting animals, the secretory granules are ready for the next predation event, containing enzymes needed for alkaline extra-oral digestion which will compose the digestive fluid, such as trypsins, astacins and chitinase. The digestive vacuoles are filled with an acidic proteolytic cocktail to the intracellular digestion composed by cathepsins L, B, F, D and legumain. Other proteins as lipases, carbohydrases, ctenitoxins and a chitolectin with a perithrophin domain were also detected. Evolutionarily, a large gene duplication of cathepsin L occurred in Arachnida with the sequences from ticks being completely divergent from other arachnids probably due to the particular selective pressures over this group.

Abstract
Defensins are broadly present in plants, invertebrates and vertebrates, but little information is available about it in amphioxus, a protochordate holding a key phylogenetic position. In this study, a big defensin cDNA was identified from the amphioxus Branchiostoma japonicum (termed Bjbd). The cDNA contained an open reading frame (ORF) of 354 bp encoding a 117 amino acid protein, which had an N-terminal signal sequence followed by a propeptide and the mature big defensin. The mature peptide had the hydrophobic region GAAAVT(A)AA at N-terminus and the consensus pattern C-X6-C-X3-C-X13(14)-C-X4-C-C at C-terminus as well as four α-helices, four β-sheets, and three disulfide bridges (C1-C5, C2-C4 and C3-C6) in the predicted tertiary structure. This is the first big defensin gene ever identified in the phylum Chordata. Quantitative real-time PCR analysis revealed that Bjbd was constitutively expressed in most of the tissues examined, and its expression was remarkably up-regulated following the challenge with LPS, LTA, Aeromonas hydrophila and Staphylococcus aureus. Moreover, the recombinant BjBD was shown to be able to inhibit the growth of S. aureus, Escherichia coli and A. hydrophila. Taken together, these suggest that BjBD is a molecule involved in the removal of invading pathogens.
