General annotation (Comments)
| Function | Transcription factor involved in osteoblastic differentiation and skeletal morphogenesis. Essential for the maturation of osteoblasts and both intramembranous and endochondral ossification. CBF binds to the core site, 5'-PYGPYGGT-3', of a number of enhancers and promoters, including murine leukemia virus, polyomavirus enhancer, T-cell receptor enhancers, osteocalcin, osteopontin, bone sialoprotein, alpha 1(I) collagen, LCK, IL-3 and GM-CSF promoters By similarity. Inhibits MYST4-dependent transcriptional activation. Ref.7 |
| Subunit structure | Interaction with SATB2 results in enhanced DNA binding and transactivation by these transcription factors By similarity. Heterodimer of an alpha and a beta subunit. Interacts with HIVEP3 By similarity. The alpha subunit binds DNA as a monomer and through the Runt domain. DNA-binding is increased by heterodimerization. Interacts with G22P1 (Ku70) and XRCC5 (Ku80). Interacts with MYST3 and MYST4. Ref.7 Ref.6 |
| Subcellular location | |
| Tissue specificity | Specifically expressed in osteoblasts. |
| Domain | A proline/serine/threonine rich region at the C-terminus is necessary for transcriptional activation of target genes and contains the phosphorylation sites. |
| Post-translational modification | Phosphorylated; probably by MAP kinases (MAPK) By similarity. Isoform 3 is phosphorylated on Ser-340. Ref.8 |
| Involvement in disease | Defects in RUNX2 are the cause of cleidocranial dysplasia (CCD) [MIM:119600]. CCD is an autosomal dominant skeletal disorder with high penetrance and variable expressivity. It is due to defective endochondral and intramembranous bone formation. Typical features include hypoplasia/aplasia of clavicles, patent fontanelles, wormian bones (additional cranial plates caused by abnormal ossification of the calvaria), supernumerary teeth, short stature, and other skeletal changes. In some cases defects in RUNX2 are exclusively associated with dental anomalies. Ref.1 Ref.9 Ref.10 Ref.11 Ref.12 Ref.13 |
| Sequence similarities | Contains 1 Runt domain. |
