The POLR2J3 (N-term) antibody targets the N-terminal region of the POLR2J3 protein, a subunit of RNA polymerase II (Pol II), which is essential for eukaryotic transcription. Pol II is responsible for synthesizing messenger RNA (mRNA) and some small nuclear RNAs. The POLR2J3 subunit, encoded by the POLR2J3 gene, is part of the core Pol II complex and plays a role in transcription initiation and elongation. This antibody is commonly used in research to study Pol II assembly, transcriptional regulation, and its dysfunction in diseases like cancer or neurodegenerative disorders.
POLR2J3 is one of several paralogs in the POLR2J family, arising from gene duplication events, and its specific functions are still under investigation. The N-terminal region may contribute to interactions with other transcription factors or regulatory proteins. Researchers employ the POLR2J3 (N-term) antibody in techniques such as Western blotting, immunoprecipitation, and immunofluorescence to detect protein expression, localization, and post-translational modifications. Its specificity for the N-terminus helps distinguish POLR2J3 from related isoforms, aiding in studies of isoform-specific roles in cellular processes. This tool is valuable for elucidating Pol II dynamics in gene expression and disease mechanisms.
