Screening of proteins binding to FXR1P using yeast two-hybrid technique / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To screen the proteins interacting with FXR1P for functional investigation of FXR1P.</p><p><b>METHODS</b>The yeast strain AH109 transformed with the recombinant expression vector pGBKT7/FXR1 was mated with the yeast strain Y187 pretransformed with human fetal brain cDNA library. The positive clones were screened and identified by sequence analysis.</p><p><b>RESULTS</b>The recombinant expression vector pGBKT7/FXR1 was constructed successfully. Five proteins binding to FXR1P were screened from human fetal brain cDNA library using the yeast two-hybrid system, including CMAS, FTH1, GOLGA4, HSD17B1 and CSH1.</p><p><b>CONCLUSIONS</b>These results provide new clues for investigating the biological functions of FXR1P and the pathogenesis of Fragile X syndrome.</p>
