Detection of Human, Mouse, and Rat SMURF2 by Western Blot. Western blot shows lysates of MDA-MB-468 human breast cancer cell line, Neuro-2A mouse neuroblastoma cell line, and Rat-2 rat embryonic fibroblast cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human SMURF2 Monoclonal Antibody (Catalog # MAB6916) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for SMURF2 at approximately 93 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Background: SMURF2

SMURF2 (SMAD ubiquitin regulatory factor-2) is a ~86 kDa, 748 amino acid (aa) cytoplasmic E3 ubiquitin ligase that negatively regulates TGF-beta signaling by promoting proteasomal degradation of some SMAD signaling molecules. It also influences cell cycle progression, peaking during mitosis and binding MAD2L1 and NEDD9/CASL. SMURF2 contains C2, WW1-3, and HECT domains. A potential 735 aa form lacks aa 19-31 (within the C2 domain), while a 507 aa form shows an alternate start site at aa 242 (between WW1 and WW2). Within the HECT domain region used as an immunogen, human SMURF2 shares 99% and 98% aa identity with mouse and rat SMURF2, respectively.
