Summary: Predicted to enable calcium ion binding activity; cysteine-type endopeptidase inhibitor activity; and metalloendopeptidase inhibitor activity. Involved in central nervous system neuron differentiation and neuron migration. Located in neuromuscular junction; node of Ranvier; and sarcoplasm. Is active in postsynaptic density. Is expressed in several structures, including jaw; nervous system; sensory organ; skeletal musculature; and thymus primordium. Human ortholog(s) of this gene implicated in hepatocellular carcinoma. Orthologous to human SPOCK1 (SPARC (osteonectin), cwcv and kazal like domains proteoglycan 1). [provided by Alliance of Genome Resources, Nov 2024]
Expression: Biased expression in cerebellum adult (RPKM 21.7), cortex adult (RPKM 19.5) and 7 other tissues See more

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.
