Sp7 also known as Osterix is a transcription factor critical for bone formation. As a protein it has a mass of approximately 45 kDa. Sp7/Osterix is mainly expressed in osteoblasts cells responsible for new bone synthesis. The protein binds to specific DNA sequences regulating gene expression necessary for osteoblast differentiation and activity.
Sp7 or Osterix functions as an important regulator in the development of the skeletal system. It operates as part of transcriptional regulation but does not form a complex with other proteins. By activating genes involved in bone matrix composition Sp7 drives the differentiation of precursor cells into mature osteoblasts which is an essential process for normal bone growth and maintenance.
Sp7 works within the ossification pathway which is essential for bone development and regeneration. It closely interacts with Runx2 another transcription factor that plays a significant role in the regulation of osteoblast differentiation. The activity of Sp7 in this pathway ensures proper expression of bone-specific proteins including those encoded by the Spp1 and Calm genes which contribute to mineralization and calcium homeostasis.
Mutations or dysregulation of Sp7/Osterix impact conditions like osteogenesis imperfecta and osteoporosis. In these diseases impaired or excessive bone formation can occur affecting skeletal integrity. The protein's functional relationship with Runx2 is important in these contexts as both proteins together determine the balance between bone formation and resorption which when disrupted leads to pathological skeletal changes.

Terms & Conditions.
IHC image of SP7/Osterix staining in a section of formalin-fixed paraffin-embedded normal rat E15 embryo performed on a Leica BOND® system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab22552 at 1μg/ml for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
