Growth Arrest And Dna Damage-Inducible Protein Gadd45 Alpha (GADD45A) Reagents

Growth arrest and DNA damage-inducible protein GADD45 alpha

In T-cells, functions as a regulator of p38 MAPKs by inhibiting p88 phosphorylation and activity. Might affect PCNA interaction with some CDK (cell division protein kinase) complexes; stimulates DNA excision repair in vitro and inhibits entry of cells into S phase.

This gene is a member of a group of genes whose transcript levels are increased following stressful growth arrest conditions and treatment with DNA-damaging agents. The protein encoded by this gene responds to environmental stresses by mediating activation of the p38/JNK pathway via MTK1/MEKK4 kinase. The DNA damage-induced transcription of this gene is mediated by both p53-dependent and -independent mechanisms. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.
