Scientific Data

Western Blot Detection of Human TRAF‑4 antibody by Western Blot. View Larger

Detection of Human TRAF‑4 by Western Blot. Western blot shows lysates of Raji human Burkitt's lymphoma cell line and K562 human chronic myelogenous leukemia cell line. PVDF membrane was probed with 2.5 µg/mL of Human TRAF-4 Monoclonal Antibody (Catalog # MAB3279) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for TRAF-4 at approximately 53 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 4.

Background: TRAF-4

Tumor Necrosis Factor (TNF) Receptor-Associated Factors (TRAFs) are a family of adaptor proteins that interact with a wide range of cell surface receptors and participate in the regulation of cell survival, proliferation, differentiation, and stress response. TRAFs were identified by their ability to form complexes with TNF receptor superfamily members but more recently are reported to also bind to Toll/IL-1 receptor family members and mediate cellular signaling. Seven members of the TRAF family have been identified. All TRAF proteins have a homologous C-terminal TRAF domain that can bind the cytoplasmic domain of receptors as well as other TRAFs. TRAFs 2‑6 have N-terminal RING and zinc finger domains that are involved in signaling downstream events. TRAF-4, also known as CART1 and MLN62, is a 470 amino acid, 53 kDa protein. A second isoform has been identified and lacks amino acids 157‑428. TRAF-4 is unique member of the TRAF family that localizes to the nucleus and does not regulate signaling through cell surface receptors. TRAF-4 is highly expressed in human breast carcinomas and during embryogenisis.
