Predicted to enable several functions, including GTP binding activity; GTPase activity; and ubiquitin protein ligase activity. Predicted to be involved in several processes, including cell death in response to hydrogen peroxide; embryonic brain development; and protein autoubiquitination. Predicted to act upstream of or within G1 to G0 transition involved in cell differentiation; positive regulation of glial cell differentiation; and positive regulation of neuron differentiation. Predicted to be located in several cellular components, including cytoplasmic vesicle; nuclear body; and postsynaptic density. Predicted to be extrinsic component of membrane. Orthologous to human RNF112 (ring finger protein 112). [provided by Alliance of Genome Resources, Apr 2022]
