Rap1b - RAS related protein 1b

Predicted to enable GDP binding activity; GTP binding activity; and GTPase activity. Acts upstream of or within several processes, including negative regulation of regulated secretory pathway; positive regulation of ERK1 and ERK2 cascade; and small GTPase mediated signal transduction. Predicted to be located in cell-cell junction; cytosol; and lipid droplet. Predicted to be active in plasma membrane. Is expressed in brain and cerebral cortex. Orthologous to human RAP1B (RAP1B, member of RAS oncogene family). [provided by Alliance of Genome Resources, Apr 2022]
