RalA/RalB Proteins and Enzymes

The Ras-like proteins RalA and RalB are homologous proteins that constitute a grouping within the Ras superfamily of small GTPases. Like other GTPases, Ral protein activity is regulated by cycling between an active GTP-bound and an inactive GDP-bound state. Ral GTPases have been implicated in the regulation of vesicle trafficking and cell morphology.
