Scientific Data Images for Human Osterix/Sp7 MAb (Clone 764746)

Detection of Human Osterix/Sp7 antibody by Western Blot.

Detection of Human Osterix/Sp7 by Western Blot.

Western blot shows lysates of Saos-2 human osteosarcoma cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Osterix/Sp7 Monoclonal Antibody (Catalog # MAB75471) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Osterix/Sp7 at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Osterix/Sp7

Osterix, also known as Sp7, is an approximately 45 kDa transcription factor that is required for osteogenesis and bone homeostasis. Osterix cooperates with BMP-6 in the differentiation of osteoblasts from mesenchymal stem cells by regulating the transcription of several genes involved in osteoblast differentiation and function (i.e. SATB2, Collagen V, and SOST). The transcription of Osterix is induced by BMP-2, IGF-I, and parathyroid hormone, while its activity is regulated by Akt and p38 MAPK-mediated phoshorylation. Osterix contains a transactivation domain (aa 141-210) and three zinc finger domains (aa 294-318, aa 324-348, and aa 354-376). Alternative splicing generates a short isoform that lacks the N-terminal 18 amino acids. Within aa 19-288, human Osterix shares 94% aa sequence identity with mouse and rat Osterix.
