CC   -!- FUNCTION: Crystallins are the dominant structural components of the
CC       vertebrate eye lens. {ECO:0000250}.
CC   -!- SUBUNIT: Monomer. {ECO:0000250}.
CC   -!- DOMAIN: Has a two-domain beta-structure, folded into four very similar
CC       Greek key motifs.
CC   -!- SIMILARITY: Belongs to the beta/gamma-crystallin family. {ECO:0000305}.
