Predicted to enable transforming growth factor beta binding activity. Acts upstream of or within several processes, including negative regulation of bone mineralization; negative regulation of chondrocyte differentiation; and positive regulation of bone resorption. Located in extracellular region. Is expressed in several structures, including cardiovascular system; jaw; limb; respiratory system; and ventricular layer. Used to study brachyolmia-amelogenesis imperfecta syndrome. Human ortholog(s) of this gene implicated in brachyolmia-amelogenesis imperfecta syndrome and geleophysic dysplasia 3. Orthologous to human LTBP3 (latent transforming growth factor beta binding protein 3). [provided by Alliance of Genome Resources, Apr 2022]
