Function

Forms a water channel that facilitates the transport of water across cell membranes, playing a crucial role in water homeostasis in various tissues. Could also be permeable to small solutes including hydrogen peroxide, glycerol and gases such as amonnia (NH3), nitric oxide (NO) and carbon dioxide (CO2). Recruited to the ankyrin-1 complex, a multiprotein complex of the erythrocyte membrane, it could be part of a CO2 metabolon, linking facilitated diffusion of CO2 across the membrane, anion exchange of Cl(-)/HCO3(-) and interconversion of dissolved CO2 and carbonic acid in the cytosol.

Biological Context

Subcellular Location: Cell membrane (Multi-pass membrane protein)
Tissue Specificity: Detected in erythrocytes (at protein level). Expressed in a number of tissues including erythrocytes, renal tubules, retinal pigment epithelium, heart, lung, skeletal muscle, kidney and pancreas. Weakly expressed in brain, placenta and liver

Recruited to the ankyrin-1 complex, a multiprotein complex of the erythrocyte membrane, it could be part of a CO2 metabolon, linking facilitated diffusion of CO2 across the membrane, anion exchange of Cl(-)/HCO3(-) and interconversion of dissolved CO2 and carbonic acid in the cytosol (PubMed:17012249, PubMed:35835865). In vitro, it shows non-selective gated cation channel activity and may be permeable to cations like K(+) and Na(+) in vivo (PubMed:36949749, PubMed:8703053)

Subunit

Homotetramer; each monomer provides an independent water pore (PubMed:11171962, PubMed:35835865). Component of the ankyrin-1 complex in the erythrocyte, composed of ANK1, RHCE, RHAG, SLC4A1, EPB42, GYPA, GYPB and AQP1 (PubMed:35835865). Interacts with EPHB2; involved in endolymph production in the inner ear (By similarity). Identified in a complex with STOM (PubMed:23219802). Interacts (via the N-terminal) with ANK1 (via ANK 1-5 repeats) (PubMed:35835865). Interacts (via the C-terminal) with EPB42 (PubMed:35835865)
