Klotho:a protein molecule interacting with FPC protein / 中国病理生理杂志

ABSTRACT

AIM:To investigate the role of fibrocystin/polycystin (FPC) in autosomal recessive polycystic kidney disease (ARPKD) development by means of screening the protein interaction using yeast two-hybrid approach. METHODS:The constructed pGBKT7-FPC was used as the bait to screen the pre-transformed human fetal kidney cDNA expression library by yeast two-hybrid assay to obtain the host cell protein which interacted with C-terminal region of FPC. The sequence transformation screening experiment was applied to confirm the protein interactions in yeast. RESULTS:After yeast mating and co-transformation screening analysis,Klotho (KL) was selected from the host cells and the interaction between KL and FPC was further confirmed. CONCLUSION:C-terminal region of FPC can interact with KL,which probably provide the approach for further studying the role and biochemistry mechanism of FPC protein in ARPKD.
