SPT5 Antibody (17) is a mouse monoclonal IgG1 antibody that detects SPT5 in mouse, rat, human, and canine samples through applications such as western blotting (WB), immunoprecipitation (IP), and immunofluorescence (IF). SPT5, also known as DSIF p160, plays a crucial role in the regulation of transcriptional elongation, particularly in RNA polymerase II activity. SPT5 is essential for the formation of the DSIF (DRB-sensitivity-inducing factor) complex when binding to SPT4, which subsequently interacts with RNA polymerase II to modulate transcription elongation. Notably, SPT5 undergoes significant post-translational modifications, particularly phosphorylation, which affects mobility on SDS-PAGE; SPT5 from mitotic HeLa cells migrates more slowly than that from interphase cells due to enhanced phosphorylation. The C-terminal CTR1 domain of SPT5 is specifically targeted for phosphorylation by the P-TEFb complex, a modification that is vital for function as a transcriptional elongation regulator. SPT5′s ability to respond to such modifications underscores importance in the dynamic regulation of gene expression, making anti-SPT5 antibody (17) an invaluable tool for researchers studying transcriptional mechanisms and their implications in various biological processes.
