MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene forms a complex with transforming growth factor beta (TGF-beta) proteins and may be involved in their subcellular localization. Activation of this complex requires removal of the encoded binding protein. This protein also may play a structural role in the extracellular matrix. Three transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2010]
PHENOTYPE: Homozygotes for a targeted null mutation exhibit craniofacial malformations including an overshot mandible and ossification of synchondroses. Mutants develop osteosclerosis of long bones and osteoarthritis, and, in some cases, high corticosterone levels. [provided by MGI curators]
