Immunofluorescence analysis of CBX1 in 293 Cells using Anti-CBX1 Recombinant Human Biotinylated Fab (730079). 293T Cells were fixed with 3% Formaldehyde and lysed with 1% TritonX-100. Cells were then labeled with Anti-CBX1 Recombinant Human Biotinylated Fab (730079) and detected with Goat-anti-human Alexa Fluor dye F488 (green). FLAG Cells were double labeled with human Fab and detected with Goat-anti-human Alexa Fluor dye F488 (green) as well as with Mouse-anti-FLAG-M2 and detected with Goat-anti-Mouse Alexa Fluor dye F647 (yellow). The DNA in the nucleus was detected with DAPI (Blue). Control means cells were labeled only with secondary antibody Alexa Fluor Dye.

This gene encodes a highly conserved nonhistone protein, which is a member of the heterochromatin protein family. The protein is enriched in the heterochromatin and associated with centromeres. The protein has a single N-terminal chromodomain which can bind to histone proteins via methylated lysine residues, and a C-terminal chromo shadow-domain which is responsible for the homodimerization and interaction with a number of chromatin-associated nonhistone proteins. The protein may play an important role in the epigenetic control of chromatin structure and gene expression. Several related pseudogenes are located on chromosomes 1, 3, and X. Multiple alternatively spliced variants, encoding the same protein, have been identified.
