MSX2 probable play a morphogenetic role. MSX2 may play a role in limb-pattern formation. In osteoblasts, MSX2 suppresses transcription driven by the osteocalcin FGF response element (OCFRE).This gene encodes a member of the muscle segment homeobox gene family. The encoded protein is a transcriptional repressor whose normal activity may establish a balance between survival and apoptosis of neural crest-derived cells required for proper craniofacial morphogenesis. The encoded protein may also have a role in promoting cell growth under certain conditions and may be an important target for the RAS signaling pathways. Mutations in this gene are associated with parietal foramina 1 and craniosynostosis type 2.
