Predicted to enable several functions, including GTP binding activity; GTPase activity; and kinase inhibitor activity. Predicted to be involved in several processes, including Rac protein signal transduction; cytoskeleton organization; and engulfment of apoptotic cell. Predicted to be located in cytoplasm and immunological synapse. Predicted to be active in several cellular components, including cell cortex; cytoplasmic vesicle; and cytoskeleton. Human ortholog(s) of this gene implicated in epidermodysplasia verruciformis. Orthologous to human RHOH (ras homolog family member H). [provided by Alliance of Genome Resources, Apr 2022]
