■ 質粒簡介
p53-ABAI質粒是一種單雜交酵母陽性對照質粒。這個質粒具有AbA抗性因而具有很強的篩選能力，可極大地降低背景水平。
p53-AbAi is a yeast reporter vector that serves as a positive control in the Matchmaker Gold Yeast One-Hybrid Library Screening System. The vector contains a p53 binding site, located upstream of the yeast iso-1-cytochrome C minimal promoter and the AUR1-C gene, an antibiotic resistance gene that confers resistance to Aureobasidin A. Expression of AUR1-C, and thus AbA resistance, is induced by the binding of GAL4 activation domain-p53 fusion proteins to the p53 binding site upstream of AUR1-C.
p53-AbAi cannot be propagated episomally in yeast; it can only be stably maintained through integration into the host genome. Integration is accomplished via homologous recombination between the vector’s URA3 gene and the nonfunctional ura3-52 locus of the yeast strain provided in the Matchmaker Gold Yeast One-Hybrid System. URA3 is a nutritional marker that can also be used for the selection of recombinant yeast. To allow propagation and selection in E. coli, the vector also contains a Col E1 origin of replication and an ampicillin resistance gene (Ampr).
p53-AbAi is a positive control reporter vector that is designed to be used in conjunction with the autonomously replicating pGADT7-Rec vector and the p53 control cDNA provided in the Matchmaker Gold Yeast One-Hybrid Library Screening System. To perform control reactions, first linearize the p53-AbAi vector with BstBI, transform the vector into competent yeast cells, and select for integrants on SD/–Ura medium. Next, cotransform the p53 control cDNA and the SmaI-linearized pGADT7-Rec vector (provided) into competent yeast cells, and select for recombinants on SD/–Leu medium containing AbA (see the protocol in the Matchmaker Gold Yeast One-Hybrid Library Screening System User Manual for details).
Transformation of yeast with the linearized p53-AbAi vector will result in the integration of the vector into the yeast chromosome. Subsequent cotransformation of the linearized pGADT7-Rec vector and the p53 control cDNA will yield a construct, through the gap-repair method,that will constitutively express a GAL4 AD-p53 fusion protein. GAL4 AD-p53 will interact with the p53 binding sites on p53-AbAi and stimulate transcription of AUR1-C.
