P30301 MIP_HUMAN:

Expressed in the cortex and nucleus of the retina lens (at protein level) (PubMed:30790544). Major component of lens fiber gap junctions (PubMed:24120416).

描述:
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.

研究背景

功能:

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 (By similarity). Plays a role in cell-to-cell adhesion and facilitates gap junction coupling.

翻译修饰:

Subject to partial proteolytic cleavage in the eye lens core. Partial proteolysis promotes interactions between tetramers from adjoining membranes (By similarity).

Fatty acylated at Met-1 and Lys-238. The acyl modifications, in decreasing order of ion abundance, are: oleoyl (C18:1) > palmitoyl (C16:0) > stearoyl (C18:0) > eicosenoyl (C20:1) > dihomo-gamma-linolenoyl (C20:3) > palmitoleoyl (C16:1) > eicosadienoyl (C20:2).

组织特异性:

Expressed in the cortex and nucleus of the retina lens (at protein level). Major component of lens fiber gap junctions.

亚基结构:

Homotetramer. Homooctamer formed by head-to-head interaction between homotetramers from adjoining membranes. Interacts with CALM; one CALM molecule interacts with the cytoplasmic domains of two aquaporins, leading to channel closure (By similarity). Interacts (via C-terminus) with BFSP1 (via C-terminus) in aged lens fiber cells (By similarity).

蛋白家族:

Aquaporins contain two tandem repeats each containing two membrane-spanning helices and a pore-forming loop with the signature motif Asn-Pro-Ala (NPA). Each tandem repeat contains a loop and a short helix that enter and leave the lipid bilayer on the same side (By similarity).

Belongs to the MIP/aquaporin (TC 1.A.8) family.
