Scientific Data Images for Human beta-Arrestin 1 Antibody

Detection of Human beta-Arrestin 1 antibody by Western Blot.

Detection of Human beta-Arrestin 1 by Western Blot.

Western blot shows lysates of human peripheral blood mononuclear cells under reducing (R) and non-reducing (NR) conditions. PVDF membrane was probed with 2 µg/mL Rat Anti-Human beta-Arrestin 1 Monoclonal Antibody (Catalog # MAB45601) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band for beta-Arrestin 1 was detected at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: beta-Arrestin 1

The Arrestin family consists of four members: Arrestin 1 (visual Arrestin), Arrestin 2 ( beta-Arrestin 1), Arrestin 3 ( beta-Arrestin 2), and Arrestin 4 (cone Arrestin). While visual and cone Arrestins are found almost exclusively in the retina, beta-Arrestins 1 and 2 are ubiquitously expressed, and were initially described as negative regulators of G protein-coupled receptor (GPCR) signaling. More recently, beta-Arrestins have been determined to serve as scaffolds for various signaling pathways, including the MAPK cascades activating ERK2, p38 alpha, and JNK3. These beta-Arrestin scaffolds tie together the appropriate kinases in series, forming a discreet signaling module that localizes components to specific subcellular environments and facilitates greater kinase activation.
