MED18. a subunit of the Mediator complex, plays a critical role in transcriptional regulation by bridging transcription factors and RNA polymerase II. The Mediator complex, composed of 26–34 subunits in humans, acts as a molecular interface to modulate gene expression. MED18 is part of the conserved "head" module, contributing to structural stability and functional interactions. It facilitates recruitment of the complex to promoter regions, enabling chromatin remodeling and assembly of the transcriptional machinery. Studies link MED18 to diverse cellular processes, including cell cycle progression, differentiation, and stress responses. Dysregulation of MED18 is implicated in cancers, neurodegenerative diseases, and developmental disorders.
MED18 antibodies are essential tools for investigating its expression, localization, and protein interactions. These antibodies are widely used in techniques like Western blotting, immunoprecipitation, ChIP-seq, and immunofluorescence. Commercial MED18 antibodies are typically raised in rabbits or mice against specific epitopes, with validation involving knockout cell lines or siRNA-mediated depletion controls. Researchers employ them to explore MED18's role in disease mechanisms, transcriptional networks, and therapeutic targeting. Challenges include ensuring specificity due to shared homology among Mediator subunits. Recent studies also highlight MED18's involvement in DNA repair and viral infection pathways, expanding its functional relevance.
