Raf-1 Proteins and Enzymes

Raf-1 is a MAP kinase kinase kinase (MAP3K), which functions downstream of the Ras family of membrane associated GTPases to which it binds directly. The activated Raf-1 can phosphorylate and activate the dual specificity protein kinases MEK1 and MEK2, which in turn phosphorylate to activate the Serine/Threonine specific protein kinases ERK1 and ERK...
