Biotin rna pull down
WebAlthough very little is known about the mechanisms of function of noncoding RNAs, these undoubtedly involve the interaction with multiple cellular proteins. Here we describe a detailed RNA pulldown protocol for the in vitro detection of proteins specifically interacting with a long RNA molecule. WebApr 25, 2024 · The RNA-desthiobiotin is immobilized through interaction with streptavidin on magnetic beads, which are used to pull down proteins that specifically interact with the RNA of interest. Non-denatured and active proteins from the cytosolic fraction of mesothelioma cells are used as the source of proteins.

WebFeb 10, 2024 · Here, we demonstrate the step-by step optimization of pull-down for IRP (iron-responsive-element-binding protein) with a 5'-biotinylated stem-loop IRE (iron-responsive element) RNA, HuR, and AUF1 with an AU-rich RNA element and Nrf2 binding to an antioxidant-responsive element (ARE) enhancer in the human ferritin H gene. WebHere, we describe an RNA-protein pull-down assay, which enables the identification of proteins that interact with an RNA under study. As an example, we describe pull-down of proteins interacting with lncRNA ELENA1, which promotes the enrichment of MED19a on PR1 promoter to activate PR1 expression.
WebAn RNA pull-down protocol is optimized here for detection of interactions between RNA-binding proteins (RBPs) and noncoding as well as coding RNAs. An RNA fragment from androgen receptor (AR) was used as an example to demonstrate how to retrieve its RBP from lystate of primary brown adipocytes.
