GADD45G eiwit, menselijk, recombinant

GADD45G, also known as CR6, is part of the nuclear proteins to interact with various proteins whose transcript levels are raised after stressful growth arrest conditions and treatment with DNA-damaging agents. GADD45G reacts to environmental stresses by mediating activation of the p38/JNK pathway which is mediated through their protein binding and activating MTK1/MEKK4 kinase, which is an upstream activator of both p38 and JNK MAPKs. GADD45G acts as a new-age tumor suppressor however is being frequently inactivated epigenetically in multiple tumors. GADD45G mRNA expression is down-regulated in hepatocellular carcinoma. GADD45G causes cell cycle arrest at G2/M transition when transfected into Hep-G2 cells. GADD45G induction by androgens involves new protein synthesis. Overexpression of GADD45G inhibits cell growth and causes morphological modifications in prostate cell lines thus GADD45G takes part in differentiation induction by androgens.
