Ral guanine nucleotide dissociation stimulator (IPR015758)

Short name: RalGDS

Overlapping homologous superfamilies

Family relationships


RalGDS belongs to the Ral GDP dissociation stimulator (RalGDS) family [PMID: 10760592]. It has been linked to cancer [PMID: 15766660].

RalGDS family members can act both as Ras effectors and as guanine nucleotide exchange factors (GEFs) for Ral. They act downstream of Ras and bind to the GTP-bound active form of Ras or Ras family members. They also promote the GDP to GTP exchange for Ral small GTPase, member of the Ras family [PMID: 9099691]. Due to their double action, the RalGDS proteins bridge Ras and Ral [PMID: 20478380].
