Col9a2 Gene Summary [Mouse]
Predicted to enable protein homodimerization activity. Predicted to be an extracellular matrix structural constituent conferring tensile strength. Predicted to be involved in extracellular matrix organization. Located in collagen-containing extracellular matrix. Is expressed in several structures, including central nervous system; exocrine system; limb mesenchyme; sensory organ; and skeleton. Human ortholog(s) of this gene implicated in Stickler syndrome; multiple epiphyseal dysplasia 2; and osteochondrodysplasia. Orthologous to human COL9A2 (collagen type IX alpha 2 chain).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Col9a2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
