Predicted to enable cullin family protein binding activity. Predicted to contribute to ubiquitin-protein transferase activity. Predicted to be involved in chromosome passenger complex localization to spindle midzone; protein ubiquitination; and regulation of cytokinesis. Predicted to act upstream of or within cell division. Predicted to be located in polar microtubule. Predicted to be part of Cul3-RING ubiquitin ligase complex. Is expressed in several structures, including genitourinary system. Orthologous to human KLHL21 (kelch like family member 21). [provided by Alliance of Genome Resources, Apr 2022]
