The osteoinductive BMP2 signal facilitates commitment to the osteoblast phenotype by inducing several classes of early response genes. Among these are bone related HOX factors, Homeodomain (HD), RUNX and OSTERIX proteins. Here we demonstrate molecular events among BMP2 induced transcription factors that constitute a network of molecular switches on promoters of bone related genes to coordinate their temporal expression during cellular differentiation. Our studies provide evidence for (i) selective association of HOXA10, MSX2, DLX3 and DLX5 homeodomain transcription factors on Runx2 and Osteocalcin genes at stages of osteoblast maturation; and (ii) participation of these factors with RUNX2 in chromatin remodeling of bone specific genes for repression, activation, and attenuation of transcription. These findings reveal the requirement for multiple levels of control for the appropriate timing of osteoblast related gene expression.
