Function

FUNCTION: Key regulator of transforming growth factor beta (TGFB1, TGFB2 and TGFB3) that controls TGF-beta activation by maintaining it in a latent state during storage in extracellular space. Associates specifically via disulfide bonds with the Latency- associated peptide (LAP), which is the regulatory chain of TGF- beta, and regulates integrin-dependent activation of TGF-beta. {ECO:0000303|PubMed:10743502, ECO:0000303|PubMed:11104663}.;

Disease

DISEASE: Dental anomalies and short stature (DASS) [MIM:601216]: A disorder characterized by hypoplastic amelogenesis imperfecta, significant short stature, brachyolmia-like anomalies including platyspondyly with short pedicles, narrow intervertebral and interpedicular distances, rectangular-shaped vertebrae with posterior scalloping and herniation of the nuclei, and broad femoral necks. Dental anomalies include widely spaced, small, yellow teeth, oligodontia, and severely reduced to absent enamel. {ECO:0000269|PubMed:19344874}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Geleophysic dysplasia 3 (GPHYSD3) [MIM:617809]: A form of geleophysic dysplasia, a rare skeletal disease characterized by severe short stature, short hands and feet, and joint limitations. Radiologic features include delayed bone age, cone-shaped epiphyses, shortened long tubular bones, and ovoid vertebral bodies. Affected individuals have characteristic facial features including a 'happy' face with full cheeks, shortened nose, hypertelorism, long and flat philtrum, and thin upper lip. Other distinctive features include skin thickening, progressive cardiac valvular thickening often leading to an early death, toe walking, tracheal stenosis, respiratory insufficiency, and lysosomal-like storage vacuoles in various tissues. GPHYSD3 inheritance is autosomal dominant. {ECO:0000269|PubMed:27068007}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
