FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Crystallins are separated into two classes: taxon-specific and ubiquitous. The former class is also called phylogenetically-restricted crystallins. The latter class constitutes the major proteins of vertebrate eye lens and maintains the transparency and refractive index of the lens. This gene encodes a taxon-specific crystallin protein that binds NADPH and has sequence similarity to bacterial ornithine cyclodeaminases. The encoded protein does not perform a structural role in lens tissue, and instead it binds thyroid hormone for possible regulatory or developmental roles. Mutations in this gene have been associated with autosomal dominant non-syndromic deafness. [provided by RefSeq, Sep 2014]
PHENOTYPE: At the euthyroid state, homozygotes display a normal growth curve, heart rate and hearing ability but have significantly reduced serum concentrations of triiodothyronine (T3) and thyroxine (T4). [provided by MGI curators]
