| Abstract |
GADD34 is one of a subset of proteins induced after DNA damage or cell growth arrest. To examine the function of GADD34, we used the yeast two-hybrid system to clone the protein that interacts with murine GADD34. As bait we used the product of the partial GADD34 cDNA, including the regions rich in proline, glutamic acid, serine and threonine (PEST) and gamma(1)34.5 regions. A cDNA clone, named GAHSP40, which is a mouse DnaJ family protein with a high similarity to human HLJ1 was cloned. The interaction between GADD34 and GAHSP40 in cultured cells was confirmed by a co-immunoprecipitation experiment and in NIH 3T3 cells by two-hybrid analysis in vivo. For binding of the two proteins, the gamma(1)34.5-similar region of GADD34 was necessary; however, the PEST region was also involved and the C-terminus of GAHSP40, but not the J-domain, was important. GAHSP40 was detected in all mouse tissues examined, but a different transcript was found in the testis. Both GADD34 mRNA and GAHSP40 mRNA were significantly elevated by treatment with methyl methanesulphonate, although the time courses were different. In addition, both GAHSP40 and GADD34 mRNA were induced by heat shock. |
