Predicted to enable cullin family protein binding activity. Predicted to contribute to ubiquitin protein ligase activity. Predicted to be involved in several processes, including cellular protein metabolic process; heart development; and podosome assembly. Predicted to act upstream of or within myoblast differentiation; protein polyubiquitination; and skeletal muscle cell differentiation. Predicted to be located in Z disc. Predicted to be part of Cul5-RING ubiquitin ligase complex. Orthologous to human ASB2 (ankyrin repeat and SOCS box containing 2). [provided by Alliance of Genome Resources, Apr 2022]
