Western blot analysis of extracts from Hela (lane 2(20μg) or lane 3(40μg)) and K562 (lane 4(20μg) or lane 5(40μg)) using TRAF2 (HY-P80357) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Rabbit IgG-HRP Secondary Antibody (1/10,000) was used for 1 hour at room temperature. -
Immunohistochemical analysis of paraffin-embedded Mouse spleen tissue using TRAF2 Antibody. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HY-P80357, 1/100) in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background

Function
E3 ubiquitin-protein ligase that regulates activation of NF-kappa-B and JNK and plays a central role in the regulation of cell survival and apoptosis (PubMed:10346818, PubMed:11784851, PubMed:12917689, PubMed:15383523, PubMed:18981220, PubMed:19150425, PubMed:19810754, PubMed:19918265, PubMed:19937093, PubMed:20047764, PubMed:20064526, PubMed:20385093, PubMed:20577214, PubMed:22212761). Catalyzes 'Lys-63'-linked ubiquitination of target proteins, such as BIRC3, IKBKE, MLST8, RIPK1 and TICAM1 (PubMed:23453969, PubMed:28489822). Is an essential constituent of several E3 ubiquitin-protein ligase complexes, where it promotes the ubiquitination of target proteins by bringing them into contact with other E3 ubiquitin ligases (PubMed:15383523, PubMed:18981220). Regulates BIRC2 and BIRC3 protein levels by inhibiting their autoubiquitination and subsequent degradation; this does not depend on the TRAF2 RING-type zinc finger domain (PubMed:11907583, PubMed:19506082). Plays a role in mediating activation of NF-kappa-B by EIF2AK2/PKR (PubMed:15121867). In complex with BIRC2 or BIRC3, promotes ubiquitination of IKBKE (PubMed:23453969). Acts as a regulator of mTORC1 and mTORC2 assembly by mediating 'Lys-63'-linked ubiquitination of MLST8, thereby inhibiting formation of the mTORC2 complex, while facilitating assembly of the mTORC1 complex (PubMed:28489822). Required for normal antibody isotype switching from IgM to IgG (By similarity)

Homotrimer (PubMed:8069916). Heterotrimer with TRAF1 (PubMed:8069916). Heterotrimer with TRAF3 (via TRAF domain) (PubMed:15383523, PubMed:20447407). The domain containing the RING-type and the first TRAF-type zinc finger can also form homodimers (in vitro) (PubMed:19810754). Interacts with TNFRSF1B/TNFR2 (PubMed:10206649, PubMed:7639698, PubMed:8069916). Interacts with TNFRSF5/CD40 (PubMed:9718306). Interacts with TNFRSF4, TNFRSF7/CD27, TNFRSF8/CD30, TNFRSF9/CD137, TNFRSF11A/RANK, TNFRSF13B/TACI, TNFRSF14, TNFRSF16/NGFR, TNFRSF17/BCMA, TNFRSF18/AITR, TNFRSF19/TROY, TNFRSF19L/RELT and EDAR (PubMed:10037686, PubMed:10411888, PubMed:10514511, PubMed:10809768, PubMed:10880535, PubMed:11035039, PubMed:38354704, PubMed:8627180, PubMed:9153189, PubMed:9418902, PubMed:9488716, PubMed:9607925, PubMed:9692890, PubMed:9774460). Stimulation of TNF-alpha receptor TNFRSF1A leads to the formation of two distinct signaling complexes. Plasma membrane-bound complex I is composed of TNFRSF1A, TRADD, RIPK1, TRAF2 and BIRC2/c-IAP1 or BIRC3 which interacts with CHUCK/IKK-alpha, IKBKB/IKK-beta and IKBKG/IKK-gamma promoting cell survival (PubMed:18981220, PubMed:21307340). Subsequently, TRADD, RIPK1 and TRAF2 dissociate from TNFRSF1A and form cytoplasmic complex II with FADD and caspase CASP8 promoting cell apoptosis (PubMed:21307340). Interacts with TRADD (PubMed:10892748). Identified in a complex with TNFRSF1A, RIPK1 and IKBKB/IKK-beta (PubMed:18981220). Interacts with RIPK2 (PubMed:9705938). Interacts with BIRC2 and BIRC3 N-terminus; a single BIRC2 or BIRC3 molecule interacts with a heterotrimer formed by TRAF1 and TRAF2, or a TRAF2 homotrimer (PubMed:11907583, PubMed:19506082, PubMed:20385093, PubMed:20447407). Identified in a complex composed of TRAF2, TRAF3, BIRC2 and BIRC3 (By similarity). Interacts with BIRC2; the interaction promotes BIRC2 stability (PubMed:19506082). Interaction with BIRC2 and/or BIRC3 is essential for ubiquitination of IKBKE, degradation of NFKBIA and activation of NF-kappa-B (By similarity). Within complex I, phosphorylated TRAF2 interacts (via 'Lys-63'-linked polyubiquitin chains) with CHUCK/IKK-alpha, IKBKB/IKK-beta, IKBKG/IKK-gamma TAB2, TAB3 and TAK1 in response to TNF-alpha stimulation (PubMed:19150425). Within complex I, interacts with UXT isoform 1 (via TPQE motif); the interaction prevents the recruitment of FADD and CASP8/caspase 8 to complex I (PubMed:21307340). Forms a complex composed of TNFRSF8/CD30 or TNFRSF1B/TNFR2, and TRAF1, TRAF2 and E3 ligase TRAIP (PubMed:9104814).

Interacts with TRPC4AP (By similarity). Interacts with MAP3K1/MEKK1, MAP3K5/ASK1 and MAP3K11/MLK3 in response to TNF-alpha stimulation; the interaction leads to JNK activation and interaction with MAP3K5 is inhibited by PRMT1 (PubMed:10346818, PubMed:19918265, PubMed:22095282, PubMed:9774977). Component of a complex composed of MAP3K14/NIK BIRC3 and TRAF3; the interaction leads to BIRC2/3-mediated ubiquitination of TRAF3 upon CD40 engagement in a TRAF2-dependent manner (By similarity).

Interacts with deubiquitinating enzyme CYLD; the interaction results in the deubiquitination and inactivation of TRAF2 (PubMed:12917691). Interacts with SIAH2; the interaction leads to TRAF2 ubiquitination and degradation (PubMed:12411493). Interacts with E2 conjugating enzyme UBE2N/Ubc13, E3 ligase ITCH and RNF11 in response to TNF-alpha stimulation (By similarity). Interacts with ubiquitin-editing enzyme TNFAIP3/A20 in response to TNF-alpha stimulation; the interaction promotes TRAF2 dissociation from UBE2N/Ubc13, ITCH, RNF11 and TAX1BP1 and prevents prolonged TRAF-2 ubiquitination (By similarity). Interacts with TAX1BP1 in response to TNF-alpha stimulation; the interaction promotes TRAF2 dissociation from UBE2N/Ubc13 and TNFAIP3/A20, and prevents prolonged TRAF-2 ubiquitination (By similarity).
