Cryab - crystallin, alpha B Gene

Rattus norvegicus

Also known as AACRYA

Gene ID: 25420 | Gene type: protein coding

About Cryab

Summary

This gene encodes subunit b, one of two subunits of alpha-crystallin, which is a high molecular weight, soluble aggregate and is a member of the small heat shock protein family. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions. It acts as a molecular chaperone and is the major protein in the eye lens, maintaining the transparency and refractive index of the lens. Alternate promoter usage results in different transcript variants encoding the same protein. [provided by RefSeq, Sep 2014]
