EDNRB (Endothelin B Receptor) is a member of the beta-family of rhodopsin receptors. It binds endothelin 1, 2, and 3 and is found on endothelial cells where it mediates vasodilation. Mature human EDNRB is a 7-transmembrane glycoprotein that is 416 amino acids (aa) in length. It contains a 75 aa N-terminal extracellular region (aa 27-101), and a 44 aa C-terminal cytoplasmic domain. There are three EDNRB variants that affect aa 27-101. One shows a 90 aa N-terminal extension, a second shows the same 90 aa N-terminal substitution coupled with a deletion of aa 268-398, and a third shows proteolytic cleavage between Arg64-Ser65. Over aa 27-101, human EDNRB shares 67% and 97% aa sequence identity with mouse and canine EDNRB, respectively.

Scientific Data Images for Human EDNRB/Endothelin R Type B Antibody
Detection of EDNRB/Endothelin R Type B in A172 Human Cell Line by Flow Cytometry.
A172 human glioblastoma cell line was stained with Human EDNRB/Endothelin R Type B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4496, filled histogram) or isotype control antibody (Catalog # 5-001-A, open histogram), followed by NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # NL010).
Detection of EDNRB in HEK293 Human Cell Line Transfected with Human EDNRB and eGFP by Flow Cytometry.
HEK293 human embryonic kidney cell line transfected with either (A) human EDNRB or (B) irrelevant protein and eGFP was stained with Sheep Anti-Human EDNRB Affinity Purified Polyclonal Antibody (Catalog # AF4496) followed by Allophycocyanin-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # F0127). Quadrant markers were set based on control antibody staining (Catalog # 5-001-A). View our protocol for Staining Membrane-associated Proteins.
