    Summary
    Enables identical protein binding activity. Acts upstream of or within lens development in camera-type eye. Is expressed in brain; eye; gut gland; and pancreas primordium. Human ortholog(s) of this gene implicated in cataract 42. Orthologous to human CRYBA2 (crystallin beta A2). [provided by Alliance of Genome Resources, Dec 2024]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
