Molecular genetic characterisation and expression profiling of calpain 3 transcripts in red sea bream (Pagrus major).

Calpains (CAPNs) belong to the papain superfamily of cysteine proteases, and they are calcium-dependent cytoplasmic cysteine proteases that regulate a variety of physiological processes. We obtained the sequence of CAPN3 from an NGS-based analysis of Pagrus major (PmCAPN3) and confirmed the conserved molecular biological properties in the predicted amino acid sequence. The amino acid sequence and predicted domains of CAPN3 were found to be highly conserved in all of the examined species, and one catalytic domain and four calcium binding sites were identified.

Molecular characterization and gene expression data of liver expressed antimicrobial Peptide-2 (LEAP-2) isolated from rock bream ().

Antimicrobial peptides (AMPs) are known to play a role as a first line of defence against microbial invasion. Liver Expressed Antimicrobial Peptides-2 (LEAP-2) is one of the AMPs. LEAP-2 includes four highly conserved cysteine residues and belongs to a cysteine-rich peptides group.

Data on CXC chemokine ligand 10(CXCL10) expression and activation in red sea bream during bacterial and viral infection.

CXCL10 plays an important role in angiogenesis and inhibits the differentiation of endothelial cells into capillaries. It also plays an important role in the generation and transmission of effector T cell responses and the recruitment of T cells to inflammatory sites. In this article, we constructed cDNAs to identify and analyse the CXCL10 domain, and performed multiple alignments and a phylogenetic analysis to determine homology with other animals.

The atypical chemokine receptor 4 in red sea bream (Pagrus major): Molecular characterization and gene expression analysis.

Atypical chemokine receptor 4 (ACKR4) is regulated by cytokines, binds chemokines and regulates the chemokine gradient. We verified the cDNA sequence by confirming ACKR4 from red sea bream (PmACKR4) by next generation sequencing (NGS) and analysed the molecular characteristics and gene expression profile. In the analysis using the predicted amino acid sequence of PmACKR4, a highly conserved G protein-coupled receptor 1 region and two cysteine residues were identified and included in the ACKR4 teleost cluster in the phylogenetic analysis.

Data on molecular characterization and expression profiles of the NF-κB repressing factor gene in red sea bream ().

Nuclear factor-kappaB (NF-κB) repressing factor (NKRF) specifically inhibits the transcriptional activity of NF-κB protein. The PmNKRF cDNA is composed of 757 amino acid residues. Alignment analysis revealed that the G-patch and R3H domains are conserved in different organisms.

Characterization of gene expression profiles and functional analysis of peptidoglycan recognition protein 2 from rock bream (Oplegnathus fasciatus).

Peptidoglycan recognition protein 2 (PGRP2) is a Zn-dependent peptidase that plays important roles in binding to microbial components of the cell membrane, inducing phagocytosis and antimicrobial activity. Rock bream (Oplegnathus fasciatus) PGRP2 (RbPGRP2) was identified in the intestine by next generation sequencing (NGS) analysis. The open reading frame (ORF) the RbPGRP2 cDNA (470 amino acid residues) contains a peptidoglycan recognition protein domain (residues 300 to 446).
