Binding of RUNX2, presumably associated with CBFB, to OSE2 (osteoblast specific element 2) sites in the promoter of the ITGA5 stimulates ITGA5 transcription. Integrin alpha-5, encoded by the ITGA5 gene, promotes adhesion of breast cancer cells to the bone, thus facilitating formation of bone metastases (Li et al. 2016).
