    motifs/domains
  • a RING domain within its N-terminal regulatory region
  • a SWIM (SWI2/SNF2 and MuDR) domain, proximal to the RING domain, directly associating with the JUN DNA-binding domain, and required for MAP3K1-dependent JUN ubiquitylation
  • a kinase catalytic domain, hybrid between those of serine/threonine and tyrosine protein kinases
  • a PHD domain Ring-type zinc finger, required for JNK activation and efficient induction of apoptosis by drugs causing cytoskeletal disruption
  • a docking site, a stretch of about 20 amino acids immediately on the C-terminal side of the MAPKK catalytic domain
  • conjugated PhosphoP

    basic FUNCTION
  • exercizing an antiapoptotic function as activator of C-Jun amino-terminal kinase (JNK) in response to changes in the microtubule cytoskeleton and extra signal-regulated protein kinase (ERK)
  • stimulating MADH2 mediated transcriptional activation in endothelial cells
  • acting as an E3 ubiquitin-ligase (by its PHD domain) and mediating ubiquitination and degradation of ERK1/2
  • involved in apoptosis as caspase-3 substrate and in the induction of apoptosis by genotoxins but not by microtubule altering drugs
  • important downstream component in the MAPK cascade that serves to integrate a variety of extracellular signals, and REG3A activity can be modulated through ERK signaling pathways by extracellular signals
  • required with TRAF6 by HSPPD2A to activate NF-kappaB and mitogen-activated protein kinases that are critical for the optimal induction of type I interferons
  • transmits wound signals, leading to the transcriptional activation of genes involved in extracellular matrix homeostasis, epithelial cell migration, and wound reepithelialization
  • involved in the canonical Wnt signalling pathway and positively regulates expression of Wnt target genes
  • activates the MAPK JNK and is required for microtubule inhibitor-induced apoptosis in B cells
  • novel role for MAP3K1 in which it crosstalks with the cell cycle regulatory pathways in the prevention of retina malformation and degeneration
  • integrates developmental signals for eyelid closure
  • CELLULAR PROCESS cell life, cell death/apoptosis

  • binding ceramide
  • regulatory kinase for REG3A
  • physically interacted with CRTC1 and stimulated its nuclear translocation
  • interacting with STK10 (MAP3K1 and STK10 may have opposing roles in regulating the CD28RE/AP1 element of IL2)
  • AXIN1 inter-actor in JUN NH(2)-terminal kinase pathway
  • DCAF7 required to allow coupling of MAP3K1 to DYRK1 and HIPK2 (DCAF7 is a novel scaffold protein regulating kinase signalling by HIPK2 and MAP3K1)
  • forms with JUN, a regulatory axis that orchestrates morphogenesis by integrating two different networks of eyelid closure signals

  • Mekk1 knockout mice; Map3k1 within the syntenic region was expressed in the embryonic mouse gonad prior to, and after, sex determination
  • mice lacking Map3k1 are fertile and exhibit no overt abnormalities of testis development
  • Map3K1-deficient mice exhibit increased proliferation and apoptosis, and Muller glial cell overproduction in the developing retinas
