Background

Function
Apoptosis signal-regulating kinase 1 (ASK1) is a member of the mitogen-activated protein kinase (MAP3K) family which acts as an upstream regulator for the activation of p38 MAPK and c-Jun N-terminal kinase (JNK) . Under normal physiological conditions, ASK1 is maintained in an inactive state through binding to the reduced form of thioredoxin. However, during pathological conditions which induce intracellular production of reactive oxygen species (e.g., mitochondrial or endoplasmic reticulum stress), thioredoxin is oxidized and dissociates from ASK1 facilitating activation of ASK1 and downstream p38 MAPK and JNK signaling that can cause tissue injury .

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)
