    Summary
    Enables calcium ion binding activity and integrin binding activity. Involved in calcium ion homeostasis and photoreceptor cell maintenance. Located in several cellular components, including muscle tendon junction; photoreceptor inner segment; and sarcolemma. Is expressed in several structures, including brain; gut; inner ear; integumental system; and skeletal musculature. Used to study autosomal recessive nonsyndromic deafness 48. Human ortholog(s) of this gene implicated in Usher syndrome type 1J and autosomal recessive nonsyndromic deafness 48. Orthologous to human CIB2 (calcium and integrin binding family member 2).

    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.
