Introduction

ASF1A is part of the H3/H4 family of histone chaperone proteins corresponding to the anti-silencing function-1 gene in yeast. ASF1A is an important element of the histone donor complex that functions in nucleosome assembly. ASF1A interacts with histones H3 and H4, and functions together with a chromatin assembly factor during DNA replication and repair. Deletion of ASF1A in yeast and Drosophila confers sensitivity to various DNA damaging agents and inhibitors of DNA replication, increases genomic instability and sister chromatid exchange, and activates the DNA damage checkpoint.

Description

ASF1A produced in E.Coli is a single,non-glycosylated polypeptide chain containing 204 amino acids (1-240 a.a.) and having a molecular mass of 27 kDa.
ASF1A is fused to 37 amino acid His Tag and purified by proprietary chromatographic techniques.

Source

Escherichia Coli.
