Ubiquitously expressed SP1 belongs to the Sp family of transcription factors with antitumor activity, responsible for early embryonic development. It consists of a DNA binding domain, with three zinc fingers, and two glutamine and serine/threonine-rich trans-activation domains.
Synonyms: Anti-Transcription factor Sp1 antibody produced in rabbit
MDL Number: MFCD02097425
Storage: -20C
Application: Anti-SP1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: SP1 (transcription factor) stability, as well as transcriptional activity is highly regulated by various post-transcriptional modifications. It plays a vital role in chromatin remodeling and regulating gene expression during transcription. SP1 also plays a critical role in vascular endothelial growth factor (VEGF) overexpression.
