COL9A3

Collagen alpha-3(IX) chain is a is_associated_with::protein that in humans is encoded by the COL9A3 is_associated_with::gene.

Function
This gene encodes one of the three alpha chains of type IX is_associated_with::collagen, the major collagen component of is_associated_with::hyaline cartilage. Type IX collagen, a heterotrimeric molecule, is usually found in tissues containing type II collagen, a fibrillar collagen. Mutations in this gene are associated with is_associated_with::multiple epiphyseal dysplasia.
