P78369

功能描述

形成旁细胞通道:在紧密连接链中聚合,形成穿过链的阳离子和阴离子选择性通道,通过称为旁细胞紧密连接通透性的过程传递上皮通透性。 {ECO:0000269|PubMed:19383724, ECO:0000269|PubMed:28686597, ECO:0000269|PubMed:35650657, ECO:0000269|PubMed:36008380}.; FUNCTION: [Isoform 1]: 形成阳离子选择性旁细胞通道。在汗腺和肾亨利氏袢升支粗段(TAL)中,它控制旁细胞钠通透性,这对于正常的汗液产生和肾功能至关重要(PubMed:19383724, PubMed:28686597, PubMed:28771254, PubMed:35650657, PubMed:36008380)。 {ECO:0000269|PubMed:19383724, ECO:0000269|PubMed:28686597, ECO:0000269|PubMed:28771254, ECO:0000269|PubMed:35650657, ECO:0000269|PubMed:36008380}.; FUNCTION: [Isoform 2]: 形成阴离子选择性旁细胞通道。在肾近曲小管中,它传递相对于碳酸氢根阴离子的选择性氯离子通透性,这是肾氯离子重吸收和盐稳态所必需的。 {ECO:0000250|UniProtKB:Q9Z0S6, ECO:0000269|PubMed:19383724, ECO:0000269|PubMed:36008380}.

组织特异性

Expressed in the kidney, eccrine sweat glands and in all layers of the epidermis. In the kidney, it is detected in the thick ascending limb of Henle's loop (TAL) (PubMed:28686597, PubMed:28771254). In the sweat glands, it is expressed in cells from secretory portions, corresponding to the clear cells (PubMed:28686597).
