CC -!- FUNCTION: Acts as a transcriptional regulator in bone development.
CC Represses the ALPL promoter activity and antagonizes the stimulatory
CC effect of DLX5 on ALPL expression during osteoblast differentiation.
CC Probable morphogenetic role. May play a role in limb-pattern formation.
CC In osteoblasts, suppresses transcription driven by the osteocalcin FGF
CC response element (OCFRE). Binds to the homeodomain-response element of
CC the ALPL promoter. {ECO:0000269|PubMed:15383550,
CC ECO:0000269|PubMed:1677742}.
CC -!- SUBUNIT: Interacts with MINT. Interacts with XRCC6 (Ku70) and XRCC5
CC (Ku80) (By similarity). {ECO:0000250}.
CC -!- INTERACTION:
CC Q03358; Q9QYH6: Maged1; NbExp=5; IntAct=EBI-1801354, EBI-1801274;
CC Q03358; P25233: Ndn; NbExp=3; IntAct=EBI-1801354, EBI-1801080;
CC -!- SUBCELLULAR LOCATION: Nucleus.
CC -!- TISSUE SPECIFICITY: Expressed in mesenchymal tissue in the developing
CC spinal cord and limbs.
CC -!- INDUCTION: Up-regulated by BMP2. {ECO:0000269|PubMed:15383550}.
CC -!- SIMILARITY: Belongs to the Msh homeobox family. {ECO:0000305}.
