    basic FUNCTION
  • serine/threonine protein kinase activating SEK and MEK
  • RIPK1-dependent recruitment of MAP3K3 plays a specific role in TNF-alpha signaling
  • may enhance transcription
  • mediates activation of the NFKappaB, AP1 and DDIT3 transcriptional regulators
  • is required for T cell immunity
  • specific role of MAP3K3 in mediating the TCR signals for IFNG production
  • CCM2/MAP3K3-mediated regulation of RHO signalling is required for maintenance of neurovascular integrity
  • plays an intrinsic role in embryonic vascular development
  • CCM2L and CCM2 cooperate to regulate the activity of MAP3K3
  • role of MAP3K3 in mediating NFKB1 signalling to promote the proliferation, invasion, migration, and chemotherapeutic resistance of ovarian carcinoma cells
  • is known to accelerate the RAS pathway of cellular proliferation
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling signal transduction
    ERK and SAPK pathway
    a component
  • ternary complex CCM1/CCM2/MAP3K3
  • associating with SQSTM1 in a complex and regulating NF-kappaB activation (Nakamura 2010)
    • INTERACTION
    DNA
    RNA
    small molecule cofactor, nucleotide,
  • ATP binding
  • cofactor Mg2+
    • protein
  • cooperates with MAP3K7, leading to NF-kappaB activation
  • interacting with MAP2K5 and SPAG9
  • activate the MAPK7 signal pathway by phosphorylating and activating MEK2K5 (Hu 2007)
  • MAP3K2 and MAP3K3 negatively regulated transforming growth factor-beta (TGFB1)-mediated Th cell differentiation
  • XIAP directly interacts with MAP3K3 and competes with PB1 domain-mediated binding to MAP2K5
  • harmonin homology domain (HHD)of CCM2 mediating interaction with the N terminus of MAP3K3
  • both CCM2L and CCM2 interfere with MAP3K3 activation and its ability to phosphorylate MAP2K5, a downstream target
  • specific interactions between YAP1 and proteins in the ERK5 pathway, such as MEK kinase 3 (MAP3K3) and MAPK7
