REG3A（regenerating family member 3 alpha），癌症关联基因，基因ID：5068，该基因编码一种可能参与细胞增殖或分化的胰腺分泌蛋白。与c型凝集素超家族相似。该基因在胰腺炎症和肝癌发生过程中表达增强成熟蛋白还具有抗菌活性交替剪接导致编码相同蛋白质的多个转录变体。[由RefSeq提供，2014年11月]This gene encodes a pancreatic secretory protein that may be involved in cell proliferation or differentiation. It has similarity to the C-type lectin superfamily. The enhanced expression of this gene is observed during pancreatic inflammation and liver carcinogenesis. The mature protein also functions as an antimicrobial protein with antibacterial activity. Alternate splicing results in multiple transcript variants that encode the same protein.[provided by RefSeq， Nov 2014]。
