Predicted to enable ubiquitin-like ligase-substrate adaptor activity. Predicted to be involved in proteasome-mediated ubiquitin-dependent protein catabolic process; protein K48-linked ubiquitination; and regulation of Rac protein signal transduction. Predicted to be located in nucleus. Predicted to be part of Cul3-RING ubiquitin ligase complex. Predicted to be active in cytoplasm. Orthologous to human KBTBD6 (kelch repeat and BTB domain containing 6).
