克劳丁-16 (旁细胞素-1) (PCLN-1)

Q9Y5I7

功能描述

形成旁细胞通道:与CLDN19共组装形成紧密连接链,链中具有阳离子选择性通道,通过称为旁细胞紧密连接通透性的过程传递上皮通透性 (PubMed:16234325, PubMed:18188451, PubMed:28028216)。参与维持肾单位沿线的离子梯度。在Henle氏袢的升支粗段 (TAL) 中,促进钠从间质腔室向腔内的旁细胞通透,有助于产生驱动旁细胞镁和钙重吸收的腔内正跨上皮电位 (PubMed:10390358, PubMed:11518780, PubMed:14628289, PubMed:16528408, PubMed:28028216)。 {ECO:0000269|PubMed:10390358, ECO:0000269|PubMed:11518780, ECO:0000269|PubMed:14628289, ECO:0000269|PubMed:16234325, ECO:0000269|PubMed:16528408, ECO:0000269|PubMed:18188451, ECO:0000269|PubMed:28028216}。
