凡纳滨对虾Crustin基因生物信息学分析OA

This study performed a bioinformatics analysis of the Litopenaeus vannamei Crustin gene.The cDNA sequence was obtained from NCBI,and multiple online tools were used to predict its physicochemical properties,structural features,transmembrane regions,signal peptide,subcellular localization,phosphorylation sites,and protein interactions.The results showed that the protein has a molecular weight of approximately 15.31 kDa with an isoelectric point of 8.00,is generally stable,and exhibits slight hydrophobicity.Both secondary and tertiary structures were predominantly random coils.No transmembrane regions were detected,but a potential signal peptide was identified,suggesting it may be a secretory protein.Subcellular localization predicted it to be mainly distributed in the cytoplasm with potential extracellular transport.Phosphorylation analysis revealed multiple sites potentially involved in several signaling pathways.Protein interaction analysis indicated associations with antimicrobial proteins containing WAP domains.These findings provide a theoretical basis for further investigation into the structural characteristics and immune-related functions of Crustin.
