Enables protein kinase binding activity. Acts upstream of or within negative regulation of G1/S transition of mitotic cell cycle; negative regulation of cyclin-dependent protein serine/threonine kinase activity; and negative regulation of lymphocyte differentiation. Located in mitochondrion and nucleus. Is expressed in dorsal root ganglion; gallbladder; liver; trigeminal ganglion; and vagus ganglion. Human ortholog(s) of this gene implicated in Parkinson's disease and Parkinson's disease 15. Orthologous to human FBXO7 (F-box protein 7). [provided by Alliance of Genome Resources, Apr 2022]
