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. Predicted to be located in Z disc and nucleolus. Predicted to be part of SCF ubiquitin ligase complex. Predicted to be active in cytosol and nucleus. Is expressed in several structures, including adipose tissue; genitourinary system; gut; musculature; and nervous system. Orthologous to human FBXL22 (F-box and leucine rich repeat protein 22).
