Summaries for MIP Gene

Entrez Gene Summary for MIP Gene

  • Major intrinsic protein is a member of the water-transporting aquaporins as well as the original member of the MIP family of channel proteins. The function of the fiber cell membrane protein encoded by this gene is undetermined, yet this protein is speculated to play a role in intracellular communication. The MIP protein is expressed in the ocular lens and is required for correct lens function. This gene has been mapped among aquaporins AQP2, AQP5, and AQP6, in a potential gene cluster at 12q13.

GeneCards Summary for MIP Gene

MIP (Major Intrinsic Protein Of Lens Fiber) is a Protein Coding gene. Diseases associated with MIP include cataract 15, multiple types and early-onset posterior polar cataract. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and Aquaporin-mediated transport. GO annotations related to this gene include transporter activity and structural constituent of eye lens. An important paralog of this gene is AQP1.

UniProtKB/Swiss-Prot for MIP Gene

  • Water channel (PubMed:24120416). 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 (By similarity). Plays a role in cell-to-cell adhesion and facilitates gap junction coupling (PubMed:24120416).
