Enables BMP binding activity; integrin binding activity; and protease binding activity. Acts upstream of or within several processes, including animal organ development; chondrocyte proliferation; and vasculature development. Located in extracellular space. Part of protein-containing complex. Is expressed in several structures, including connective tissue; embryo mesenchyme; notochord; placenta; and skeletal system. Used to study multiple epiphyseal dysplasia and pseudoachondroplasia. Human ortholog(s) of this gene implicated in carpal tunnel syndrome; multiple epiphyseal dysplasia 1; osteochondrodysplasia; and pseudoachondroplasia. Orthologous to human COMP (cartilage oligomeric matrix protein). [provided by Alliance of Genome Resources, Apr 2022]
