GADD45A produced in E.Coli is a single, non-glycosylated polypeptide chain containing 173 amino acids (1-165 a.a.) and having a molecular mass of 19.4kDa.GADD45A is fused to 8 amino acids His Tag at C-terminus and purified by proprietary chromatographic techniques.
Growth arrest and DNA Damage-Inducible Protein (GADD45A) binds both Cdks and PCNA. GADD45A is involved in DNA replication and repair. GADD45A stimulates DNA excision repair in vitro and inhibits entry of cells into S phase. GADD45A may serve as a link between p53-dependent cell cycle checkpoint and DNA repair. The GADD45A gene belongs to a group of genes whose transcript levels are increased following stressful growth arrest conditions and treatment with DNA-damaging agents. GADD45A responds to environmental stresses by mediating activation of the p38/JNK pathway via MTK1/MEKK4 kinase. GADD45A binds to proliferating cell nuclear antigen.
