Cartilage associated protein

Cartilage associated protein is a protein that in humans is encoded by the CRTAP gene.[1][2]

Function

The protein encoded by this gene is similar to the chicken and mouse CRTAP genes. The encoded protein is a scaffolding protein that may influence the activity of at least one member of the cytohesin/ARNO family in response to specific cellular stimuli.[1]

Clinical significance

Mutations in the CRTAP gene are associated with osteogenesis imperfecta, types VII and IIB, a connective tissue disorder characterized by bone fragility and low bone mass.[3][4]
