This gene encodes a member of the crystallin family of proteins that are localized to the refractive structure of vertebrate eye lenses. The protein encoded by this gene is unique in that it has both beta and gamma crystallin protein motifs. Alternative splicing of this gene results in multiple transcript variants.
