<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Appears to regulate cell growth through interactions with the extracellular matrix and cytokines. Binds calcium and copper, several types of collagen, albumin, thrombospondin, PDGF and cell membranes. There are two calcium binding sites; an acidic domain that binds 5 to 8 Ca2+ with a low affinity and an EF-hand loop that binds a Ca2+ ion with a high affinity.

Osteogenesis imperfecta 17 (OI17)1 Publication
The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionAn autosomal recessive form of osteogenesis imperfecta, a connective tissue disorder characterized by low bone mass, bone fragility and susceptibility to fractures after minimal trauma. Disease severity ranges from very mild forms without fractures to intrauterine fractures and perinatal lethality. Extraskeletal manifestations, which affect a variable number of patients, are dentinogenesis imperfecta, hearing loss, and blue sclerae.
