PRSS1基因编码丝氨酸蛋白酶1(也称为阳离子胰蛋白酶原),主要在胰腺中表达,其功能是生成胰蛋白酶,帮助消化蛋白质。PRSS1属于丝氨酸蛋白酶家族,该家族成员通常具有催化三联体(组氨酸、天冬氨酸和丝氨酸)结构,参与多种生理过程如消化、凝血和免疫反应。PRSS1的突变,尤其是R122H和N29I突变,会导致胰蛋白酶过早激活,引发遗传性胰腺炎,表现为反复发作的胰腺炎症、疼痛和胰腺组织损伤。PRSS1过表达会增加胰蛋白酶活性,可能导致胰腺自消化和炎症,而表达降低则可能影响蛋白质消化效率。此外,PRSS1突变还与慢性胰腺炎和胰腺癌风险增加相关。该基因属于胰蛋白酶原基因家族,家族成员在结构上高度保守,均参与消化酶原的激活级联反应。
This gene encodes a trypsinogen, which is a member of the trypsin family of serine proteases. This enzyme is secreted by the pancreas and cleaved to its active form in the small intestine. It is active on peptide linkages involving the carboxyl group of lysine or arginine. Mutations in this gene are associated with hereditary pancreatitis. This gene and several other trypsinogen genes are localized to the T cell receptor beta locus on chromosome 7. [provided by RefSeq, Jul 2008]
此基因编码一种胰蛋白酶原,这是胰蛋白酶家族丝氨酸蛋白酶的成员。这种酶是由胰腺分泌和在小肠中裂解以它的活性形式。它是在涉及赖氨酸或精氨酸的羧基肽键活性。在这种基因突变与遗传性胰腺炎有关。这种基因和其他几个胰蛋白酶基因定位于T细胞受体β基因上[由RefSeq的,2008年7月提供] 7号染色体
