Testing Data
(Representative blot from a previous lot. 10ug acid-extracted HeLa cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with MBS604246 (0.8ug/ml). Proteins were visualized using an IgG (HRP) goat anti-mouse and a chemiluminescence detection system. Arrow indicates HP1a (~29kD).)

NCBI and Uniprot Product Information
NCBI Description
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 (CSD) which is responsible for the homodimerization and interaction with a number of chromatin-associated nonhistone proteins. The encoded product is involved in the formation of functional kinetochore through interaction with essential kinetochore proteins. The gene has a pseudogene located on chromosome 3. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Jul 2008]
Uniprot Description
HP1 alpha: Component of heterochromatin that recognizes and binds histone H3 tails methylated at 'Lys-9' (H3K9me), leading to epigenetic repression. In contrast, it is excluded from chromatin when 'Tyr-41' of histone H3 is phosphorylated (H3Y41ph). Can interact with lamin-B receptor (LBR). This interaction can contribute to the association of the heterochromatin with the inner nuclear membrane. Involved in the formation of functional kinetochore through interaction with MIS12 complex proteins. Interacts with SUV420H1 and SUV420H2. Interacts with HP1BP3. Interacts directly with ATRX, CHAF1A, LBR, NIPBL, SP100, STAM2 and TRIM28 via the chromoshadow domain. Can interact directly with CBX3 via the chromoshadow domain. Interacts with histone H3 methylated at 'Lys- 9'. Interacts with BAHD1, MIS12 and DSN1. Interacts with POGZ; POGZ and PXVXL motif-containing proteins such as INCENP and TRIM28 compete for interaction with CBX5. Interacts with INCENP and TRIM24. Interacts with JC virus agnoprotein; this interaction induces the dissociation of CBX5 from LBR, resulting in destabilization of the nuclear envelope. Interacts with CHAMP1. Interacts with ASXL1.

Product Notes
The HP1a cbx5 (Catalog #AAA6243483) is an Antibody produced from Mouse and is intended for research purposes only. The product is available for immediate purchase. The Heterochromatin Protein 1, alpha (HP1a) (FITC) reacts with Human, Mouse and may cross-react with other species as described in the data sheet. AAA Biotech's Heterochromatin Protein 1, alpha can be used in a range of immunoassay formats including, but not limited to, Chromatin Immunoprecipitation (ChIP), Immunohistochemistry (IHC), Western Blot (WB). Researchers should empirically determine the suitability of the HP1a cbx5 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Heterochromatin Protein 1, alpha, Monoclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
