Gel mobility shift scanning of pectin-inducible promoter from Penicillium griseoroseum reveals the involvement of a CCAAT element in the expression of a polygalacturonase gene

Previous reports have described pgg2, a polygalacturonase-encoding gene of Penicillium griseoroseum, as an attractive model for transcriptional regulation studies, due to its high expression throughout several in vitro growth conditions, even in the presence of non-inducing sugars such as sucrose. A search for regulatory motifs in the 5' upstream regulatory sequence of pgg2 identified a putative CCAAT box that could justify this expression profile. This element, located 270 bp upstream of the translational start codon, was tested as binding target for regulatory proteins. Analysis of a 170 bp promoter fragment by electrophoretic mobility shift assay (EMSA) with nuclear extracts prepared from mycelia grown in pectin-containing culture medium revealed a high...

Autores: Wang,Yong; Huang,Wenhua; Peng,Daizhi; Hu,Yuanbin.
In this work, several major procedures of the electrophoretic mobility shift assay (EMSA) were modified including swift extraction of the nucleic protein, labeling of the probe and radioautography. The modified assay required shorter time, simplified the nucleic protein extraction, increased the radioactivity of the labeling probe, skipped the tedious process of gel drying, and produced clear images. Its results were comparable, reproducible and stable. It thus has merited for wide application.
