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.

Heterochromatin protein 1 alpha acts as a modulator of gene silencing. It is part of a larger protein complex that contains various chromatin modifiers responsible for maintaining the silent state of certain genes. By mediating these interactions HP1 alpha helps regulate transcription replication timing and DNA repair processes. This regulation is essential for the structural maintenance of heterochromatin and plays a part in chromosomal stability.
HP1 alpha also known as HP1a or HP1 protein is a well-studied member of the heterochromatin protein 1 family. It plays a mechanical role in chromatin organization and gene regulation by binding to histone H3 when it's methylated at lysine 9 (H3K9me). This protein has a molecular mass of approximately 22-25 kDa. HP1 alpha is commonly expressed in the nuclei of eukaryotic cells where it localizes to heterochromatin regions and influences chromatin compaction.
HP1 alpha is integral in the epigenetic regulation pathway along with other well-known proteins including SUV39H1 and SUV39H2 which are histone methyltransferases. HP1 alpha also links to the DNA damage response pathway where it recruits repair factors to maintain genomic integrity. Through these pathways HP1 alpha interacts closely with proteins like BRCA1 emphasizing its role in cellular homeostasis and response to DNA damage.
Researchers associate HP1 alpha with cancer and developmental disorders. Alterations in HP1 alpha expression or function can lead to disruptions in chromatin organization contributing to oncogenesis by affecting tumor suppressor genes. Furthermore HP1 alpha links to disorders like ICF syndrome through its relationship with the DNA methylation process where it interacts with proteins such as DNMT3B. Understanding these connections provides insights into therapeutic approaches targeting epigenetic modifications in disease contexts.

Terms & Conditions.
Overlay histogram showing HeLa cells stained with ab185018 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab185018, 1/50 dilution) for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) Alexa Fluor® 488 used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.
Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
This antibody gave a positive signal in HeLa fixed with 4% formaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

The cells were then incubated with ab185018 (Alexa Fluor® 488) at a working dilution of 1 in 50 overnight at +4°C (shown in green). Alexa Fluor® 350 WGA was used at a 1/200 dilution and incubated for 1h with the cells, to label plasma membranes (shown in blue). Nuclear DNA was labelled in red with 1.25 μM DRAQ5™ (ab108410).
