Abstract
Proliferating cell nuclear antigen (PCNA) is a crucial eukaryotic replication accessory factor in the regulation of DNA synthesis, which is always used as a proliferation marker for haematopoiesis in vertebrates. In the present study, a homologue of PCNA (named as CgPCNA) with a conserved N-terminal PCNA domain and a C-terminal PCNA domain was identified from oyster Crassostrea gigas. The deduced amino acid sequence of CgPCNA shared 85.4% and 86.6% similarities with the PCNAs identified in Mus musculus and Homo sapiens, respectively. CgPCNA was firstly clustered with PCNAs from molluscs, and then with PCNAs from arthropods to form a group falling into the invertebrate clade in the phylogenic tree. The mRNA transcripts of CgPCNA were detected in all tested tissues with higher expression level in gonad, gills and haemolymph. They were also detected in granulocytes, semi-granulocytes and agranulocytes with no significant differences, but the protein level of CgPCNA in agranulocytes was significantly higher (3.67-fold, p < 0.05) than that in granulocytes. In the haemocytes, CgPCNA was mainly distributed in the nucleus and less in the cytoplasm of haemocytes. CgPCNA protein was observed at the tubule lumen regions of gills vessels, and especially colocalized with the EdU signals. After lipopolysaccharide (LPS) and Vibrio splendidus stimulation, the expression level of CgPCNA mRNA in haemocytes was significantly (p < 0.05) up-regulated at 6 h and 12 h, which was 13.87-fold and 3.89-fold of that in control, respectively. In the oysters treated with the recombinant protein CgAstakine (rCgAstakine), the protein abundance of CgPCNA was enhanced in agranulocytes and gills, while no significant change was observed in semi-granulocytes and granulocytes. These results collectively indicated that CgPCNA was highly expressed in the newborn agranulocytes and the potential haematopoietic sites, and it might be applied as a marker for haemocytes proliferation in oysters.

Abstract
DNA replication requires processivity factors that allow replicative DNA polymerases to extend long stretches of DNA. Some DNA viruses encode their own replicative DNA polymerase, such as the white spot syndrome virus (WSSV) that infects decapod crustaceans but still require host replication accessory factors. We have determined by X-ray diffraction the three-dimensional structure of the Pacific white leg shrimp Litopenaeus vannamei Proliferating Cell Nuclear Antigen (LvPCNA). This protein is a member of the sliding clamp family of proteins, that binds DNA replication and DNA repair proteins through a motif called PIP-box (PCNA-Interacting Protein). The crystal structure of LvPCNA was refined to a resolution of 3 Å, and allowed us to determine the trimeric protein assembly and details of the interactions between PCNA and the DNA. To address the possible interaction between LvPCNA and the viral DNA polymerase, we docked a theoretical model of a PIP-box peptide from the WSSV DNA polymerase within LvPCNA crystal structure. The theoretical model depicts a feasible model of interaction between both proteins. The crystal structure of shrimp PCNA allows us to further understand the mechanisms of DNA replication processivity factors in non-model systems.

Abstract
Proliferating cell nuclear antigen (PCNA), a member of the sliding clamp family of proteins, interacts specifically with DNA replication and repair proteins through a small peptide motif called the PCNA-interacting protein or PIP box. PCNA is recognized as one of the key proteins involved in DNA metabolism. In the present study, the recombinant PCNA from Litopenaeus vannamei (LvPCNA) was heterologously overexpressed and purified using metal ion-affinity chromatography. Crystals suitable for diffraction grew overnight using the hanging-drop vapour-diffusion method. LvPCNA crystals belong to space group C2 with unit-cell parameters a=144.6, b=83.4, c=74.3 Å, β=117.6°. One data set was processed to 3 Å resolution, with an overall Rmeas of 0.09 and a completeness of 93.3%. Initial phases were obtained by molecular replacement using a homology model of LvPCNA as the search model. Refinement and structural analysis are underway. This report is the first successful crystallographic analysis of a marine crustacean decapod shrimp (L. vannamei) proliferating cell nuclear antigen.

Abstract
Proliferating cell nuclear antigen (PCNA) is the eukaryotic sliding clamp that tethers DNA polymerase to DNA during replication. The full-length cDNA of the Pacific white shrimp Litopenaeus vannamei PCNA (LvPCNA) was cloned and encoded a protein of 260 amino acids that is highly similar to other Crustacean PCNAs. The theoretical shrimp PCNA structure has all the domains that are necessary for its interaction with template DNA and DNA polymerase. RT-PCR analysis showed that LvPCNA is expressed mainly in muscle and hemocytes and much less in hepatopancreas and gills. LvPCNA mRNA levels are not statistically different in muscle from healthy and challenged shrimp with the white spot syndrome virus (WSSV). In contrast, the mRNA levels of the viral DNA polymerase show a biphasic pattern with expression at 6 h post-infection and later at 24 and 48 h. These results suggest that in shrimp muscle LvPCNA levels are steadily kept to allow viral replication and that WSSV DNA polymerase (WSSV-DNApol) is more responsive towards later stages of infection. More knowledge of the DNA replication machinery would result in a better understanding of the mechanism and components of viral replication, since the WSSV genome does not have all the components required for assembly of a fully functional replisome.
