Preferred Label : p38 MAPK Signaling Pathway BioCarta;
NCIt related terms : p38 MAPK Signaling Pathway;
Alternative definition : BIOCARTA: p38 MAPKs are members of the MAPK family that are activated by a variety
of environmental stresses and inflammatory cytokines. Stress signals are delivered
to this cascade by members of small GTPases of the Rho family (Rac, Rho, and Cdc42).
As with other MAPK cascades, the membrane-proximal component is a MAPKKK, typically
a MEKK or a mixed lineage kinase (MLK). The MAPKKK phosphorylates and activates MKK3/5.
The p38 MAPK kinase. MKK3/6 can also be activated directly by ASK1, which is stimulated
by apoptotic stimuli. P38 MAK is involved in regulation of Hsp27 and MAPKAP-2 and
several transcription factors including ATF2, STAT1, Max/Myc complex, MEF-2, ELK-1,
and indirectly CREB via activation of MSK1. (This definition may be outdated - see
