Summary
Enables GTPase activity. Involved in several processes, including cellular bud site selection; cytogamy; and positive regulation of Rho protein signal transduction. Located in several cellular components, including cellular bud neck; incipient cellular bud site; and vacuolar membrane. Human ortholog(s) of this gene implicated in thrombocytopenia. Orthologous to several human genes including RAP1A (RAP1A, member of RAS oncogene family). [provided by Alliance of Genome Resources, Nov 2024]

NP_011668.3
  • Ras-type GTPase; required for bud site selection during both axial and bipolar budding, for morphological changes in response to mating pheromone, and for efficient cell fusion; recruits Cdc24p to the incipient bud site, activating its guanyl-nucleotide exchange factor activity and the Rho-like GTPase, Cdc42p; localizes to the plasma membrane, the incipient bud site, polarized growth sites, the cell division site and the vacuole membrane; Ras superfamily member similar to mammalian Rap GTPases
