|Other Names||Chromobox protein homolog 3, HECH, Heterochromatin protein 1 homolog gamma, HP1 gamma, Modifier 2 protein, CBX3|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP13718c was selected from the Center region of CBX3. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||Seems to be involved in transcriptional silencing in heterochromatin-like complexes. Recognizes and binds histone H3 tails methylated at 'Lys-9', leading to epigenetic repression. May contribute to the association of the heterochromatin with the inner nuclear membrane through its interaction with lamin B receptor (LBR). Involved in the formation of functional kinetochore through interaction with MIS12 complex proteins. Contributes to the conversion of local chromatin to a heterochromatin-like repressive state through H3 'Lys-9' trimethylation, mediates the recruitment of the mehtyltransferases SUV39H1 and/or SUV39H2 by the PER complex to the E-box elements of the circadian target genes such as PER2 itself or PER1.|
|Cellular Location||Nucleus. Note=Associates with euchromatin and is largely excluded from constitutive heterochromatin. May be associated with microtubules and mitotic poles during mitosis (Potential).|

At the nuclear envelope, the nuclear lamina andheterochromatin are adjacent to the inner nuclear membrane. Theprotein encoded by this gene binds DNA and is a component ofheterochromatin. This protein also can bind lamin B receptor, anintegral membrane protein found in the inner nuclear membrane. Thedual binding functions of the encoded protein may explain theassociation of heterochromatin with the inner nuclear membrane. Twotranscript variants encoding the same protein but differing in the5' UTR, have been found for this gene.
