An in Vivo Binding Assay for RNA-Binding Proteins Based on Repression of a Reporter Gene

An in vivo binding assay for RNA-binding proteins based on repression of a reporter gene

RNA-binding proteins: a lesson in repression.

Regulation of protein expression in neurons by controlling not only when, but where, mRNAs are translated is likely to play an important role in neuronal function. In this review I focus on the mRNA-binding proteins that control mRNA translation in neurons and how they may participate in local, synaptodendritic protein synthesis.

An Alkaline Phosphatase Reporter Gene Assay for Induction of CYP3A4 In Vitro

CYP3A4 probably has the broadest catalytic activity of any cytochrome P450. It is a crucial task to test new drug candidates in a reliable system for their ability to induce expression of this enzyme. Firstly, a total of 300 bp core distal enhancer of CYP3A4 XREM region (-7972/-7673) were amplified from human genomic DNA. The PCR product was then ligated into a human secretory alkaline phosphat...

A versatile assay for RNA-binding proteins in living cells.

RNA-binding proteins (RBPs) control RNA fate from synthesis to decay. Since their cellular expression levels frequently do not reflect their in vivo activity, methods are needed to assess the steady state RNA-binding activity of RBPs as well as their responses to stimuli. While electrophoresis mobility shift assays (EMSA) have been used for such determinations, their results serve at best as pr...
