lens epithelial protein

The ocular lens is a tissue of epithelial origin and devoid of blood vessels and nerves. Cells of the lens epithelium are responsible for the growth and maintenance of the lens through mitosis, protein synthesis, and active transport of ions and metabolites across the lens capsule. Lens epithelial protein is expressed exclusively in lens epithelial cells and may play a role in cell differentiation. [provided by RefSeq, Jul 2008]

lens intrinsic membrane protein 2, 19kDa

This gene encodes an eye lens-specific protein found at the junctions of lens fiber cells, where it may contribute to cell junctional organization. It acts as a receptor for calmodulin, and may play an important role in both lens development and cataractogenesis. Mutations in this gene have been associated with cataract formation. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]

major intrinsic protein of lens fiber

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.

lengsin, lens protein with glutamine synthetase domain

This gene encodes a protein with similarity to the GS I members of the glutamine synthetase superfamily. The encoded protein is referred to as a pseudo-glutamine synthetase because it has no glutamine synthesis activity and may function as a chaperone protein. This protein is localized to the lens and may be associated with cataract disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2009]
