Human v-raf murine sarcoma viral oncogene homolog B1 (BRAF), GenBank Accession No. NM_004333, a.a. 417-end with Val-to-Glu mutation on a.a. 600* and N-terminal GST-tag and His-tag, MW=69 kDa, expressed in Sf9 insect cells via a baculovirus expression system.*This mutation is often cited as V600E.
Host cell line: Sf9 cells
Specific activity: 150 pmol/min/ug
Background
BRAF is a member of the RAF family that is activated by members of the Ras family upon growth factor-induced stimulation. Active Ras can induce heterodimerization of cRaf and BRAF and this may explain the observed cooperativity of cRaf and BRaf in cells responding to growth factor signals (1). Activating mutations in the BRAF gene are present in a large percentage of human malignant melanomas and in a proportion of colon cancers. The vast majority of these mutations result in a valine to glutamic acid change at residue 599 within the activation segment of B-RAF (2).

Notes
Assay was performed in a kinase buffer containing 0.1 mg/ml inactive MEK1 substrate (BPS Cat# 40075) and 10 uM ATP. Reaction was done at 30°C for 30 minutes. ATP transferred was calculated using Kinase-Glo (Promega).
