    Summary
    Enables chromatin binding activity; methylated histone binding activity; and sequence-specific DNA binding activity. Involved in several processes, including neuron remodeling; regionalization; and regulation of gene expression. Located in chromatin; nucleolus; and polytene chromosome band. Part of PRC1 complex. Is expressed in several structures, including central brain primordium; embryonic/larval midgut primordium; ganglia; germline cell; and gut section. Used to study cancer. Human ortholog(s) of this gene implicated in 46,XY sex reversal 5; breast cancer; hepatocellular carcinoma; multiple myeloma; and myeloid leukemia. Orthologous to several human genes including CBX6 (chromobox 6) and CBX8 (chromobox 8). [provided by Alliance of Genome Resources, Dec 2024]
