Dimerization of two novel apoptosisinducing proteins and its function in regulating cell apoptosis

TL;DRAbstract

Asy (apoptosis/saibousi Yutsudo) is a novel apoptosis-inducing gene found in 1999 by Yutsudo group in Japan. In 2000, Qi Bing et al. cloned another novel gene, named hap (homologue of ASY protein), which encoded the ASY interacting protein, from human lung cell line (WI-38) cDNA library by using yeast two-hybrid system. It has been proved that ASY formed homodimer in yeast and human cell line, ASY and HAP formed heterodimer in yeast cells, and both induced cell apoptosis in human tumor cell lines Sao2 and CGL4. This paper showed that HAP could form homodimer in yeast cells by yeast two-hybrid system; HAP and ASY could produce heterodimer in human cell line by cross-immunoprecipitation test; by using apoptosis-testing technologies such as AnnexinV, TUNEL, DNA ladder and Flow Cytometry, the cell apoptosis in human normal or tumor cell lines transfected with hap or asy individually or cotransfected by the both was qualified or quantified. It was firstly demonstrated that ASY or HAP induce
