General annotation (Comments)

Function	Transcriptional factor involved in bone development. Acts as an immediate early BMP-responsive transcriptional activator essential for osteoblast differentiation. Stimulates ALPL promoter activity in a RUNX2-independent manner during osteoblast differentiation. Stimulates SP7 promoter activity during osteoblast differentiation. Promotes cell proliferation by up-regulating MYC promoter activity. Involved as a positive regulator of both chondrogenesis and chondrocyte hypertrophy in the endochondral skeleton. Binds to the homeodomain-response element of the ALPL and SP7 promoter. Binds to the MYC promoter. Requires the 5'-TAATTA-3' consensus sequence for DNA-binding. Ref.5 Ref.6 Ref.8
Subunit structure	Interacts with XRCC6 (Ku70) By similarity.
Subcellular location	Nucleus Ref.6.
Tissue specificity	Expressed in osteoblasts and chondrocytes. Ref.8
Developmental stage	Expressed in the otic vesicle, mandibular arch, branchial arches 2 and 3, in proximal anterior mesodermal domain in the limb, immature and proliferating chondroblasts at 14.5 dpc. Ref.8
Induction	Up-regulated by BMP2. Ref.5 Ref.6
Post-translational modification	Phosphorylated. Phosphorylation of Ser-34 and Ser-217 by MAPK14 enhances its transcriptional activity. Phosphorylation by CaMK2 increases its protein stability. Ref.6 Ref.7
Sequence similarities	Belongs to the distal-less homeobox family. Contains 1 homeobox DNA-binding domain.
