What pLDDT means and how to read it

Function

Key adapter protein that plays an essential role in JNK and NF-kappa-B activation and proinflammatory cytokines production in response to stimulation with TLRs and cytokines (PubMed:22307082, PubMed:24403530). Mechanistically, associates with the catalytic domain of MAP3K7/TAK1 to trigger MAP3K7/TAK1 autophosphorylation leading to its full activation (PubMed:10838074, PubMed:25260751, PubMed:37832545). Similarly, associates with MAPK14 and triggers its autophosphorylation and subsequent activation (PubMed:11847341, PubMed:29229647). In turn, MAPK14 phosphorylates TAB1 and inhibits MAP3K7/TAK1 activation in a feedback control mechanism (PubMed:14592977). Also plays a role in recruiting…

Subunit structure

Interacts with XIAP and BIRC7 (PubMed:11865055, PubMed:17560374). Interacts with TRAF6 and MAP3K7; during IL-1 signaling (PubMed:10094049, PubMed:10838074, PubMed:11323434, PubMed:8638164). Identified in the TRIKA2 complex composed of MAP3K7, TAB1 and TAB2 (PubMed:11460167). Interacts with TRAF6 and MAPK14; these interactions allow MAPK14 autophosphorylation (PubMed:11847341).
