Recombinant Human Mitogen-activated protein kinase 8 (MAPK8), partial

Recombinant Human Mitogen-activated protein kinase 8 (MAPK8), partial — JNK1 isoforms display different binding patterns: beta-1 preferentially binds to c-Jun, whereas alpha-1, alpha-2, and beta-2 have a similar low level of binding to both c-Jun or ATF2. Purity >90%.

Function

JNK1 isoforms display different binding patterns: beta-1 preferentially binds to c-Jun, whereas alpha-1, alpha-2, and beta-2 have a similar low level of binding to both c-Jun or ATF2. However, there is no correlation between binding and phosphorylation, which is achieved at about the same efficiency by all isoforms.

Forms a complex with MAPK8IP1 and ARHGEF28 (By similarity). Found in a complex with SH3RF1, RAC1, MAP3K11/MLK3, MAP2K7/MKK7 and MAPK8IP1/JIP1. Found in a complex with SH3RF1, RAC2, MAP3K7/TAK1, MAP2K7/MKK7, MAPK8IP1/JIP1 and MAPK9/JNK2 (By similarity). Binds to at least four scaffolding proteins, MAPK8IP1/JIP-1, MAPK8IP2/JIP-2, MAPK8IP3/JIP-3/JSAP1 and SPAG9/MAPK8IP4/JIP-4 (PubMed:15693750). These proteins also bind other components of the JNK signaling pathway. Interacts with TP53 and WWOX (PubMed:12514174). Interacts with JAMP (By similarity). Interacts with HSF1 (via D domain and preferentially with hyperphosphorylated form); this interaction occurs under both normal growth conditions and immediately upon heat shock (PubMed:10747973). Interacts (phosphorylated form) with NFE2; the interaction phosphorylates NFE2 in undifferentiated cells (By similarity). Interacts with NFATC4 (PubMed:17875713). Interacts with MECOM; regulates JNK signaling (PubMed:10856240). Interacts with PIN1; this interaction mediates MAPK8 conformational changes leading to the binding of MAPK8 to its substrates (PubMed:21660049). Interacts with GRIPAP1 (PubMed:17761173). Interacts with POU5F1; phosphorylates POU5F1 at 'Ser-355'. Interacts with STMN2, STMN3 and STMN4 (By similarity). Interacts with HSF4 (PubMed:16581800)
