Background: GADD45 alpha (Growth arrest and DNA damage-inducible protein 45 alpha) is a 19 kDa member of the GADD45 family of proteins. It is ubiquitously expressed, and induced by DNA damage. Upon induction, GADD45 alpha binds to PCNA, stimulates DNA excision repair, and initiates G2 cell cycle arrest. Human GADD45 alpha is 165 amino acids (aa) in length. It is reported to dimerize with GADD45-beta and -gamma, and to homo-dimerize, -trimerize and -tetramerize via residues 33?61 and 133?165. There is one splice variant that shows a Ser substitution for aa 14?49. GADD45 alpha is 55% aa identical to GADD45-beta and -gamma, and shares 94% aa identity with mouse GADD45 alpha.
