CC   -!- FUNCTION: Serine/threonine-protein kinase involved in various processes
CC       such as p38/mapk14 stress-activated MAPK cascade, DNA damage response
CC       and regulation of cytoskeleton stability. Acts as an activator of the
CC       p38/MAPK14 stress-activated MAPK cascade by mediating phosphorylation
CC       and subsequent activation of upstream MAP kinase kinases. In response
CC       to DNA damage, involved in the G2/M transition DNA damage checkpoint by
CC       activating the p38/MAPK14 stress-activated MAPK cascade (By
CC       similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
