Biochem/physiol Actions

GADD45A (growth arrest and DNA-damage-inducible, alpha) gene encodes a protein that belongs to a group of genes that are expressed under stressful growth arrest conditions and upon treatment with DNA-damaging agents such as methylmethane sulfonate and UV radiation. The protein mediates activation of the p38/JNK pathway via MTK1/MEKK4 kinase upon environmental stress. It inhibits entry of cells into S phase by activating DNA excision repair in vitro. It plays a crucial role in cell cycle checkpoints, DNA repair, and genome integrity maintenance.

Growth arrest and DNA damage inducible α (GADD45A) miRNAs are differentially expressed in osteosarcoma. It interacts with proliferating cell nuclear antigen (PCNA), aurora A kinase and histones. GADD45A improves the cytotoxic effect of the drug temozolomide (TMZ) in glioblastoma multiforme (GBM).
