"Raf-1 phosphorylates MEK1 on two serine residues, Ser 218 and Ser222 [XREF_BIBR] MEK1 phosphorylates tyrosine and threonine residues in the ERK activation loop."

rlimsp
"Raf-1 forms a stable complex with Mek1 and activates Mek1 by serine phosphorylation."

sparser
"After activation of EGFR signaling, key downstream steps involve phosphorylation by RAF1 kinase of two distinct serine residues on both MEK1 and MEK2 ( xref )."
