## Abstract Binding of 1α,25‐dihydroxy vitamin D~3~ to the C‐terminal ligand‐binding domain (LBD) of its receptor (VDR) induces a conformational change that enables interaction of VDR with transcriptional coactivators such as members of the p160/SRC family or the DRIP (vitamin D receptor‐interactin
The 1α,25-dihydroxy Vitamin D3 receptor preferentially recruits the coactivator SRC-1 during up-regulation of the osteocalcin gene

1a,25-dihydroxy vitamin D3 has a major role in the regulation of the bone metabolism as it promotes the expression of key bone-related proteins in osteoblastic cells. In recent years it has become increasingly evident that in addition to its well-established genomic actions, 1a,25-dihydroxy vitamin
## Abstract 1α,25‐dihydroxy vitamin D~3~ (vitamin D~3~) has an important role during osteoblast differentiation as it directly modulates the expression of key bone‐related genes. Vitamin D~3~ binds to the vitamin D~3~ receptor (VDR), a member of the superfamily of nuclear receptors, which in turn i
