Predicted to enable GTPase activity; guanyl ribonucleotide binding activity; and magnesium ion binding activity. Predicted to be involved in several processes, including Rap protein signal transduction; actin cytoskeleton reorganization; and microvillus assembly. Predicted to act upstream of or within establishment of protein localization; negative regulation of cell migration; and positive regulation of protein autophosphorylation. Predicted to be located in cytosol; plasma membrane; and recycling endosome membrane. Orthologous to human RAP2A (RAP2A, member of RAS oncogene family).
