| basic FUNCTION
| Spemann organizer binding and inactivating BMP4 and other TGFB family members |
|
involved in the joint formation and in skeletogenesis |
|
playing a role in creating morphogenetic gradients |
|
required for induction of the hair follicles growth phase in postnatal skin (through the modulation of BMP4) |
|
soluble BMP antagonists, regulating the action of BMPs on mesenchymal precursor cells, partially through a feedback type of inhibition |
|
bone morphogenetic protein antagonist promoting skin tumorigenesis via stimulation of the Wnt and Shh signaling pathways (Sharov 2009) |
|
may contribute to the myelofibrotic process characterized by bone marrow stromal reaction including collagen fibrosis, osteosclerosis, and angiogenesis (Andrieux 2007) |
|
NOG and GREM1 cooperate potentialy to maintain a BMP signaling-free zone that is a crucial prerequisite for Hh-mediated sclerotome induction  |
