All aspects of RNA metabolism are regulated by RNA-binding proteins (RBPs) that directly associate with the RNA. Some aspects of RNA biology such as RNA abundance can be readily assessed using standard hybridization technologies. However, identification of RBPs that specifically associate with selected RNAs has been more difficult, particularly when(More)
Immunoprecipitation of mRNA-protein complexes is a method that can be used to study RNA binding protein (RBP)–RNA interactions. In this protocol, an antibody targeting an RBP of interest is used to immunoprecipitate the RBP and any interacting molecules from a cell lysate. Reverse transcription followed by PCR is then used to identify individual mRNAs(More)
To understand the role of RNA-binding proteins (RBPs) in the regulation of gene expression, methods are needed for the in vivo identification of RNA-protein interactions. We have developed the peptide nucleic acid (PNA)-assisted identification of RBP technology to enable the identification of proteins that complex with a target RNA in vivo. Specific regions(More)
Cellular internalization is a highly regulated process controlled by proteins in the plasma membrane. Large and hydrophilic compounds, in particular, face difficulties conquering the plasma membrane barrier in order to gain access to intracellular environment. This puts serious constrains on the drug industry since many drugs are hydrophilic. Several(More)
