The JNK and p38 members of this group of enzymes relay signals from cytokines and other stressors.
In the high-osmolarity glycerol pathway, one of these proline-directed molecules lies immediately downstream from the scaffold Psb2. Proteins in this group are differentiated from one another near residue 180, at the phosphorylation lip, Persistent activation of one of these proteins is implicated in late-phase long-term potentiation. Ras exhibits its oncogenic effects via a pathway named for this enzyme. These proteins are activated at threonine and tyrosine residues by dual-specificity kinases, such as (*) MEK1, which phosphorylates ERK, a member of this group. The JNK and p38 members of this group of enzymes relay signals from cytokines and other stressors. For 10 points, name this class of serine/threonine kinases that participates in namesake cascades.
