Scientific Data

Western Blot Detection of Human iRHOM2/RHBDF2 antibody by Western Blot. View Larger

Detection of Human iRHOM2/RHBDF2 by Western Blot. Western blot shows lysates of LoVo human colorectal adenocarcinoma cell line and MCF-7 human breast cancer cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human iRHOM2/RHBDF2 Monoclonal Antibody (Catalog # MAB10048) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for iRHOM2/RHBDF2 at approximately 90 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: iRHOM2/RHBDF2

Human Inactive rhomboid protein 2 (RHBDF2 or IRHOM2) is a highly conserved seven-transmembrane Rhomboid protease-like protein which is inactive, it has no protease activity, but has been implicated in the secretion of several ligands of the epidermal growth factor receptor (EGFR), probably by regulating trafficking and stability of key protein membrane like ADAM17 and STING. The RHBDF2 protein plays an important role in the secretion of tumor necrosis factor alpha and has been implicated in familial esophageal cancer. Gain-of-function (GOF) mutations in the RHBDF2 gene constitutively activate EGFR signaling to cause tylosis with esophageal cancer syndrome.
