Lens fiber major intrinsic protein

UniProtKB accession:  Q6J8I9

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Water channel. Channel activity is down-regulated by CALM when cytoplasmic Ca(2+) levels are increased. May be responsible for regulating the osmolarity of the lens. Interactions between homotetramers from adjoining membranes may stabilize cell junctions in the eye lens core. Plays a role in cell-to-cell adhesion and facilitates gap junction coupling (By similarity).
