Western blot analysis of extracts from Hela(lane 2(20ug) and Hela(lane 3(40ug) using ASK1 Antibody (HY-P80549) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P83730, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.

Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with QuickBlock™ Blocking Buffer for Immunol Staining for 10 min at room temperature. Cells were then incubated with NTH1 Antibody (HY-P81690) at 1/50 dilution in QuickBlock™ Blocking Buffer for Immunol Staining at 4 ℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L（HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution.

Background

Function：Serine/threonine kinase which acts as an essential component of the MAP kinase signal transduction pathway. Plays an important role in the cascades of cellular responses evoked by changes in the environment. Mediates signaling for determination of cell fate such as differentiation and survival. Plays a crucial role in the apoptosis signal transduction pathway through mitochondria-dependent caspase activation. MAP3K5/ASK1 is required for the innate immune response, which is essential for host defense against a wide range of pathogens. Mediates signal transduction of various stressors like oxidative stress as well as by receptor-mediated inflammatory signals, such as the tumor necrosis factor (TNF) or lipopolysaccharide (LPS). Once activated, acts as an upstream activator of the MKK/JNK signal transduction cascade and the p38 MAPK signal transduction cascade through the phosphorylation and activation of several MAP kinase kinases like MAP2K4/SEK1, MAP2K3/MKK3, MAP2K6/MKK6 and MAP2K7/MKK7. These MAP2Ks in turn activate p38 MAPKs and c-jun N-terminal kinases (JNKs). Both p38 MAPK and JNKs control the transcription factors activator protein-1 (AP-1)

Subcellular Localization：Cytoplasm; Endoplasmic reticulum

Expression：
Tissue_specificity:It is expressed in large quantities in the heart and pancreas.

Induction:By TNF. Inhibited by HIV-1 Nef

Isoforms & Post-Translational Modification：Q99683 has 2 isomers: Q99683-1: 154537 Da (predicted); Q99683-2: 69839 Da (predicted).
Phosphorylated at Thr-838 through autophosphorylation and by MAP3K6/ASK2 which leads to activation. Thr-838 is dephosphorylated by PPP5C. Ser-83 and Ser-1033 are inactivating phosphorylation sites, the former of which is phosphorylated by AKT1. Phosphorylated at Ser-966 which induces association of MAP3K5/ASK1 with the 14-3-3 family proteins and suppresses MAP3K5/ASK1 activity. Calcineurin (CN) dephosphorylates this site. Also dephosphorylated and activated by PGAM5. Phosphorylation at Ser-966 in response to oxidative stress is negatively regulated by PPIA/CYPA (PubMed:26095851);Ubiquitinated (PubMed:16038411, PubMed:17220297, PubMed:29186683). Tumor necrosis factor (TNF) induces TNFR2-dependent ubiquitination, leading to proteasomal degradation (PubMed:17220297). Ubiquitinated by RC3H2 in a TRIM48-dependent manner (PubMed:29186683);Methylation at Arg-78 and Arg-80 by PRMT1 promotes association of MAP3K5 with thioredoxin and negatively regulates MAP3K5 association with TRAF2, inhibiting MAP3K5 activation (PubMed:22095282). Methylation is blocked by ubiquitination of PRMT1 by TRIM48 (PubMed:29186683)

Subunit：Homodimer when inactive. Binds both upstream activators and downstream substrates in multimolecular complexes. Part of a cytoplasmic complex made of HIPK1, DAB2IP and MAP3K5 in response to TNF (PubMed:15310755, PubMed:15701637, PubMed:17210579, PubMed:17389591). This complex formation promotes MAP3K5-JNK activation and subsequent apoptosis. Interacts with SOCS1 which recognizes phosphorylation of Tyr-718 and induces MAP3K5/ASK1 degradation in endothelial cells. Interacts with the 14-3-3 family proteins such as YWHAB, YWHAE, YWHAQ, YWHAH, YWHAZ and SFN (PubMed:10411906, PubMed:15023544, PubMed:15094778). Interacts with ARRB2, BIRC2, DAB2IP, IGF1R, MAP3K6/ASK2, PGAM5, PIM1, PPP5C, SOCS1, STUB1, TRAF2, TRAF6 and TXN (PubMed:10688666, PubMed:11090355, PubMed:11689443, PubMed:12556535, PubMed:12813029, PubMed:15310755, PubMed:16038411, PubMed:16129676, PubMed:16407264, PubMed:17220297, PubMed:17724081, PubMed:18408005, PubMed:19590015, PubMed:19749799, PubMed:9564042, PubMed:9774977). Interacts with ERN1 in a TRAF2-dependent manner (PubMed:14749717). Interacts with calcineurin subunit PPP3R1 (By similarity). Interacts with PPM1L (PubMed:17456047). Interacts (via N-terminus) with RAF1 and this interaction inhibits the proapoptotic function of MAP3K5 (PubMed:11427728). Interacts with DAB2IP (via N-terminus C2 domain); the interaction occurs in a TNF-alpha-dependent manner (PubMed:15310755). Interacts with DUSP13A; may positively regulate apoptosis (PubMed:20358250). Interacts with DAXX (PubMed:9743501). Interacts with RC3H2 (PubMed:24448648). Interacts with PPIA/CYPA (PubMed:26095851). Interacts with PRMT1; the interaction results in MAP3K5 methylation by PRMT1 which inhibits MAP3K5 activation (PubMed:22095282). Interacts with TRAF2; the interaction is inhibited by PRMT1 (PubMed:22095282). Interacts with TRIM48 (PubMed:29186683)

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
