BRAP protein acts as a negative regulator of MAP kinase activation, inhibits the formation of the Raf/MEK complex, and may inactivate the KSR1 scaffolding protein. As a Ras-responsive E3 ubiquitin ligase, BRAP undergoes autopolyubiquitination upon Ras activation, releasing its inhibitory effect on Raf/MEK complex formation. BRAP Protein, Human is the recombinant human-derived BRAP protein, expressed by E. coli , with tag free.
