This HP1 alpha antibody was raised against a recombinant protein corresponding to full-length recombinant mouse HP1 alpha.
Rabbit serum containing 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.
HP1 (Heterochromatin protein 1) is a chromosomal protein that participates in both chromatin packaging and gene silencing. Three HP1 isoforms (α, β and γ) occur in mammals. The chromodomain (Chromatin Organization Modifier) of HP1α is responsible for binding to Histone H3 methyl Lys9, although additional factors are required to specify the HP1 targeting. The chromoshadow domain mediates interactions with a number of nuclear proteins, including SuvH39 (a Histone H3 Lysine methyltransferase), the DNA methyltransferases DNMT1 and DNMT3A or the large subunit of the chromatin assembly factor-1 (CAF-1). Dysfunction of HP1α plays a critical role in tumorigenesis, and is implicated in the invasive/metastatic phenotype of breast cancer.
Active Motif's HeLa nuclear extract (Catalog No. 36010) can be used as a positive control for HP1 alpha antibody.
