Cbx4 - chromobox 4

Predicted to enable several functions, including SUMO binding activity; SUMO ligase activity; and nucleic acid binding activity. Predicted to be involved in negative regulation of transcription, DNA-templated. Predicted to act upstream of or within negative regulation of transcription by RNA polymerase II and protein sumoylation. Predicted to be located in nuclear body. Predicted to be part of PRC1 complex. Human ortholog(s) of this gene implicated in hepatocellular carcinoma. Orthologous to human CBX4 (chromobox 4).
