Predicted to enable cyclin binding activity; identical protein binding activity; and small GTPase binding activity. Predicted to contribute to ubiquitin-protein transferase activity. Predicted to be involved in several processes, including cellular protein metabolic process; negative regulation of Rho protein signal transduction; and stress fiber assembly. Predicted to be located in endosome. Predicted to be part of Cul3-RING ubiquitin ligase complex. Is expressed in brain; heart valve; sensory organ; and skeleton. Orthologous to human TNFAIP1 (TNF alpha induced protein 1). [provided by Alliance of Genome Resources, Apr 2022]
