Gene: COL2A1 (collagen type II alpha 1 chain) Homo sapiens
Symbol: COL2A1
Name: collagen type II alpha 1 chain
Description: Exhibits MHC class II protein binding activity; platelet-derived growth factor binding activity; and proteoglycan binding activity. Involved in several processes, including collagen fibril organization; embryonic skeletal joint morphogenesis; and sensory perception of sound. Localizes to collagen type II trimer and extracellular space. Implicated in Stickler syndrome; bone disease (multiple); cleft palate; eye disease (multiple); and multiple epiphyseal dysplasia with myopia and deafness.
Type: protein-coding
RefSeq Status: REVIEWED
