Summary: Predicted to enable calcium ion binding activity; carbohydrate binding activity; and hyaluronic acid binding activity. Involved in modulation of chemical synaptic transmission and regulation of postsynapse organization. Acts upstream of or within regulation of synapse structural plasticity. Is active in GABA-ergic synapse; glutamatergic synapse; and perisynaptic extracellular matrix. Is expressed in lower jaw; nervous system; and sensory organ. Orthologous to human NCAN (neurocan).

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.
