Lens fiber major intrinsic protein

UniProtKB accession:  P06624

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Aquaporins form homotetrameric transmembrane channels, with each monomer independently mediating water transport across the plasma membrane along its osmotic gradient (PubMed:23893133, PubMed:30790544). Specifically expressed in lens fiber cells, this aquaporin is crucial for maintaining lens water homeostasis and transparency. Beyond water permeability, it also acts as a cell-to-cell adhesion molecule, forming thin junctions between lens fiber cells that are essential for maintaining the ordered structure and transparency of the lens (By similarity).
