    Summary
    Enables chromatin binding activity; histone reader activity; and methylated histone binding activity. Involved in regulation of transcription by RNA polymerase II and subtelomeric heterochromatin formation. Located in euchromatin; nucleus; and polytene chromosome interband. Part of protein-containing complex. Is expressed in several structures, including adult head; central brain primordium; ganglia; gonad; and larval nervous system. Orthologous to human CBX1 (chromobox 1) and CBX5 (chromobox 5). [provided by Alliance of Genome Resources, Dec 2024]
