Predicted to enable several functions, including transcription coregulator activity; unmethylated CpG binding activity; and zinc ion binding activity. Predicted to be involved in protein demethylation and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within proteasome-mediated ubiquitin-dependent protein catabolic process. Predicted to be part of SCF ubiquitin ligase complex. Orthologous to human FBXL19 (F-box and leucine rich repeat protein 19). [provided by Alliance of Genome Resources, Apr 2022]
