Summation

BRAP is a negative regulator of MAPK signaling that binds KSR1 as assessed by coimmunoprecipitation. This interaction abrogates KSR1 homodimer and KSR1:RAF heterodimer formation, and disrupts the recruitment of MAP2K kinases to RAF (Methany et al, 2004; Chen et al, 2008; reviewed in Methany et al, 2009). BRAP inhibition of KSR1 is relieved in an unknown manner by autoubiquitination after RAS pathway activation (reviewed in Methany et al, 2009).
