Proximity Labeling Techniques
Proximity labeling works by fusing the decoy protein to be studied with an enzyme that nonspecifically labels the surrounding protein. The tagged proteins are called “prey” proteins. There is a rapid development of protein labeling techniques based on proximity-tagging enzymes. Biotin-dependent biotin identification (BioID) of biotin ligase mutants relying on biotin ligase (BirA), which can label lysine…
dorawest12DAP-seq: Principles, Workflow and Analysis
Overview of DAP-seq The DNA Affinity Purification Sequencing (DAP-seq) technique is an innovative method aimed at exploring the interactions between transcription factors (TFs) and genomic DNA. By simulating the interaction between TFs and their DNA binding sites in vitro, this technology reveals key DNA sequences in gene regulatory networks. In contrast to traditional Chromatin Immunoprecipitation Sequencing (ChIP-seq), DAP-seq is…
kikogarciaThe Applications of DAP-seq Technology
Transcription factors (TFs) binding to specific locations in the genome influence dynamic changes in transcription levels. Disruption of TF binding sites (TFBS) correlates with phenotypic diversity and disease states, including agriculturally important adaptive traits and various diseases like cancer. Characterizing the genome-wide binding spectrum is crucial for exploring these mechanisms. DNA affinity purification sequencing (DAP-seq) is a…
Uncovering RNA-Protein Interactions with RNA Antisense Purification and Mass Spectrometry (RAP-MS)
What is RAP-MS? RNA molecules play a vital role in cellular functions, ranging from gene expression regulation to protein synthesis. Understanding the interactions between RNA and proteins is crucial to comprehend the intricate mechanisms of cellular biology. However, identifying RNA-protein interactions can be challenging, especially for long noncoding RNAs (lncRNAs) that do not encode proteins. RNA antisense…
