B-Raf Proteins and Enzymes

The Raf serine/threonine kinases are effectors of Ras that function as MAP3Ks in the ERK phosphorylation cascade. Mammals express three Raf proteins: Raf-1 (C-Raf); A-Raf; and B-Raf, strongly expressed in fetal brain and adult cerebrum. Mice with a targeted disruption of the B-raf gene die of vascular defects during mid-gestation. B-raf mutatio...
