Recombinant Human CBX5 Protein, N-His-SUMO

Overview

Recombinant Human CBX5 Protein, also known as Chromobox protein homolog 5, is a member of the chromobox (CBX) family of proteins. It is a highly conserved protein that plays a crucial role in epigenetic regulation and gene expression. This protein is expressed in various tissues and has been found to be involved in a wide range of cellular processes, including cell proliferation, differentiation, and apoptosis. In this article, we will explore the structure, activity, and applications of Recombinant Human CBX5 Protein.

Structure of Recombinant Human CBX5 Protein

Recombinant Human CBX5 Protein is a 170 amino acid protein with a molecular weight of approximately 19 kDa. It contains a chromodomain, a chromobox (CBX) domain, and a nuclear localization signal (NLS). The chromodomain is responsible for binding to histone proteins, while the CBX domain is involved in protein-protein interactions. The NLS allows the protein to enter the nucleus and bind to DNA.

Activity of Recombinant Human CBX5 Protein

The main activity of Recombinant Human CBX5 Protein is its ability to bind to histone proteins and regulate gene expression. It specifically binds to histone H3 trimethylated at lysine 9 (H3K9me3), which is a mark of heterochromatin. This binding results in the compaction of chromatin and silencing of gene expression. Recombinant Human CBX5 Protein has also been found to interact with other proteins involved in epigenetic regulation, such as DNA methyltransferases and histone deacetylases.
