O75787

功能描述

多功能蛋白,作为肾素、前肾素细胞受体发挥作用,参与溶酶体质子转运V型ATP酶 (V-ATPase) 的组装和内溶酶体系统的酸化 (PubMed:12045255, PubMed:29127204, PubMed:30374053, PubMed:32276428)。可能通过激活ERK1和ERK2介导肾素依赖性的细胞反应 (PubMed:12045255)。通过提高肾素将AGT/血管紧张素原转化为血管紧张素I的催化效率,可能也在肾素-血管紧张素系统 (RAS) 中发挥作用 (PubMed:12045255)。通过其在V型ATP酶 (v-ATPase) 组装和溶酶体酸化中的功能,它调节蛋白降解,并可能控制对正常大脑发育、突触形态和突触传递至关重要的不同信号通路 (By similarity)。 {ECO:0000250|UniProtKB:Q9CYN9, ECO:0000269|PubMed:12045255, ECO:0000269|PubMed:29127204, ECO:0000269|PubMed:30374053, ECO:0000269|PubMed:32276428}。

组织特异性

Expressed in brain, heart, placenta, liver, kidney and pancreas. Barely detectable in lung and skeletal muscles. In the kidney cortex it is restricted to the mesangium of glomeruli. In the coronary and kidney artery it is expressed in the subendothelium, associated to smooth muscles where it colocalizes with REN. Expressed in vascular structures and by syncytiotrophoblast cells in the mature fetal placenta.
