PLA2G1B(磷脂酶A2组IB)属于分泌型磷脂酶A2(sPLA2)基因家族,该家族成员以分泌型、钙依赖性水解酶为特征,主要功能是催化甘油磷脂sn-2位酯键的水解,释放游离脂肪酸(如花生四烯酸)和溶血磷脂,参与炎症反应、信号传导和脂质代谢等过程。PLA2G1B主要在胰腺中高表达,其编码的酶作为消化酶被分泌到肠道,协助膳食脂质的消化吸收,通过分解食物中的磷脂促进脂肪吸收。该基因的突变可能导致酶活性异常,例如功能丧失突变可能引起脂肪吸收不良或脂溶性维生素缺乏,而功能获得性突变可能与慢性胰腺炎或代谢紊乱相关。PLA2G1B的过表达可能增加局部花生四烯酸水平,促进前列腺素等促炎介质的产生,与炎症性肠病或动脉粥样硬化等疾病相关;而表达降低可能影响脂质消化效率,导致营养吸收障碍。sPLA2家族共有10余个成员(如PLA2G2A、PLA2G5等),均具有保守的催化结构域和钙离子结合位点,但组织分布和功能各异,部分成员参与宿主防御、细胞凋亡等病理生理过程。研究还发现PLA2G1B可能与肥胖和胰岛素抵抗有关,因其活性影响脂质代谢途径,但具体机制仍需进一步探索。

This gene encodes a secreted member of the phospholipase A2 (PLA2) class of enzymes, which is produced by the pancreatic acinar cells. The encoded calcium-dependent enzyme catalyzes the hydrolysis of the sn-2 position of membrane glycerophospholipids to release arachidonic acid (AA) and lysophospholipids. AA is subsequently converted by downstream metabolic enzymes to several bioactive lipophilic compounds (eicosanoids), including prostaglandins (PGs) and leukotrienes (LTs). The enzyme may be involved in several physiological processes including cell contraction, cell proliferation and pathological response. [provided by RefSeq, Aug 2013]

该基因编码的磷脂酶A2(PLA 2)类的酶,它是由胰腺腺泡细胞产生的分泌成员。所编码的钙依赖性酶催化膜甘油磷脂的sn-2位置以释放花生四烯酸(AA)和溶血磷脂的水解。 AA随后被下游代谢酶转化为生物活性的几个亲脂性化合物(花生酸),包括前列腺素(PG的)和白三烯(LTS)。所述酶可能涉及几种生理过程,包括细胞收缩,细胞增殖和病理反应。 [由RefSeq的,2013年8月提供]
