Data Example

Western Blot Detection of Human, Mouse, and Rat SMURF2 antibody by Western Blot. View Larger

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.
