NCIt definition : Ral GTPase-activating protein subunit beta (1494 aa, 167 kDa) is encoded by the human
RALGAPB gene. This protein plays a role in RalGAP1- and RalGAP2-mediated activation
of Ral family GTPases.;
NCIt note : Ral GTPase-activating protein subunit beta is a component of both the heterodimeric
RalGAP1 complex with RALGAPA1 and of the heterodimeric RalGAP2 complex with RALGAPA2.
Complex formation is required for activation of Ral family GTPases. (UniProt);
