    Summary
    Predicted to enable calcium ion binding activity. Involved in regulation of synapse assembly. Acts upstream of or within axonal fasciculation and olfactory bulb development. Located in growth cone. Is active in glutamatergic synapse and postsynaptic density. Is expressed in central nervous system; dorsal root ganglion; semicircular canal epithelium; tooth; and vibrissa. Orthologous to human CRTAC1 (cartilage acidic protein 1). [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.
