Summary: Predicted to enable calcium ion binding activity. Acts upstream of or within several processes, including cartilage development; collagen fibril organization; and proteoglycan biosynthetic process. Located in basement membrane. Is active in GABA-ergic synapse; glutamatergic synapse; and perisynaptic extracellular matrix. Is expressed in several structures, including embryo mesenchyme; inner ear; limb; lower jaw; and skeletal system. Used to study achondroplasia. Human ortholog(s) of this gene implicated in spondyloepiphyseal dysplasia Kimberley type. Orthologous to human ACAN (aggrecan). [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.
