丝氨酸蛋白酶 HTRA3 (EC 3.4.21.-) (高温需求因子 A3) (妊娠相关丝氨酸蛋白酶)

P83110

功能描述

丝氨酸蛋白酶,可切割β-酪蛋白/CSN2以及几种细胞外基质(ECM)蛋白聚糖,如核心蛋白聚糖/DCN、双糖链蛋白聚糖/BGN和纤连蛋白/FN1。可能通过降解这些ECM蛋白聚糖间接抑制由TGF-beta家族蛋白介导的信号传导(根据相似性)。可能作为肿瘤抑制因子发挥作用。在体外负向调节胎盘发育过程中的滋养层细胞侵袭,并可能在体内参与胎盘发育。也可能在卵巢发育、颗粒细胞分化和黄素化中发挥作用 (PubMed:21321049, PubMed:22229724)。 {ECO:0000250|UniProtKB:Q9D236, ECO:0000269|PubMed:21321049, ECO:0000269|PubMed:22229724}。

组织特异性

Widely expressed, with highest levels in both adult and fetal heart, ovary, uterus placenta, and bladder. In the endometrium, expressed in epithelial glands and the stroma. Also present in leukocytes. Isoform 1 is predominant in heart and skeletal muscle, whereas isoform 2 is predominant in placenta and kidney.
