Product Specific Information
MA1-218 detects CBX5 from human and non-human primate samples.
CBX5 has an approximate molecular weight of 22.2 kDa.
MA1-218 has been successfully used in Western blot, immunofluorescence, and immunohistochemistry applications.
The MA1-218 Immunogen is the purified recombinant fragment of human CBX5 (AA: 1–191) expressed in E. coli.
Target Information
Heterochromatin protein-1 (HP1) is a methyl-lysine binding protein localized at heterochromatin sites, where it mediates gene silencing.
Mammalian methyltransferases that selectively methylate histone H3 on lysine-9 generate a binding site for HP1 proteins—a family of heterochromatic adaptor molecules implicated in gene silencing and chromatin structure.
High-affinity recognition of a methylated histone H3 peptide by HP1 requires a functional chromodomain, which serves as a specific interaction motif for the methyl epitope on lysine-9 of histone H3.
In vivo, heterochromatin association of HP1 proteins is lost in Suv39h double-primary mouse fibroblasts but restored after reintroduction of a catalytically active SUV39H1 HMTase.
