Predicted to enable ubiquitin protein ligase activity. Predicted to be involved in several processes, including G2/M transition of mitotic cell cycle; SCF-dependent proteasomal ubiquitin-dependent protein catabolic process; and entrainment of circadian clock by photoperiod. Predicted to act upstream of or within proteasome-mediated ubiquitin-dependent protein catabolic process. Located in Z disc. Part of SCF ubiquitin ligase complex. Orthologous to human FBXL22 (F-box and leucine rich repeat protein 22). [provided by Alliance of Genome Resources, Apr 2022]
