Summary: Predicted to enable calcium ion binding activity. Acts upstream of or within growth plate cartilage chondrocyte morphogenesis and regulation of bone mineralization. Located in extracellular matrix. Is expressed in several structures, including cartilage; genitourinary system; heart; limb; and skeleton. Orthologous to human MATN1 (matrilin 1).

The chondrocytes of the presumptive articular surface therefore appear to arise directly from a subpopulation of early chondrocytes that do not activate matrilin-1 expression rather than by redifferentiation from the flattened cells of the interzone.

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.
