Anti-NR5A2/LRH1 Antibody Picoband® Fluoro488 Conjugated

NR5A2 (nuclear receptor subfamily 5, group A, member 2) also known as liver receptor homolog-1 (LRH-1) is a protein that in humans is encoded by the NR5A2 gene. LRH-1 is a member of the nuclear receptor family of intracellulartranscription factors. LRH-1 plays a critical role in the regulation of development, cholesterol transport, bile acid homeostasis andsteroidogenesis. LRH-1 is important for maintaining pluripotence of stem cells during embryonic development. Liver receptor homolog-1 has been shown to interact with the small heterodimer partner.

Nuclear receptor subfamily 5 group A member 2; Alpha-1-fetoprotein transcription factor; B1-binding factor; hB1F; CYP7A promoter-binding factor; Hepatocytic transcription factor; Liver receptor homolog 1; LRH-1; NR5A2; B1F, CPF, FTF

E.coli-derived human NR5A2 recombinant protein (Position: K44-R237) . Human NR5A2 shares 95% amino acid (aa) sequence identity with both mouse and rat NR5A2.

Abundantly expressed in pancreas, less in liver, very low levels in heart and lung. Expressed in the Hep-G2 cell line. Isoform 1 and isoform 2 seem to be present in fetal and adult liver and Hep-G2 cells.

Binds to the sequence element 5'-AACGACCGACCTTGAG-3' of the enhancer II of hepatitis B virus genes, a critical cis-element of their expression and regulation. May be responsible for the liver-specific activity of enhancer II, probably in combination with other hepatocyte transcription factors. Key regulator of cholesterol 7-alpha-hydroxylase gene (CYP7A) expression in liver. May also contribute to the regulation of pancreas-specific genes and play important roles in embryonic development.
