Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCellular localization:\u003c\/strong\u003e Nucleus.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBackground:\u003c\/strong\u003e Transcription elongation factor SPT6 is a protein that in humans is encoded by the SUPT6H gene. SUPT6H (suppressor of Ty6 homolog), also known as SPT6, SPT6H, Tat-CT2 (Tat-cotransactivator 2 protein) or emb-5 in C. elegans, is a 1,726 amino acid protein that is highly conserved from yeast to humans. Expressed ubiquitously, SUPT6H localizes to the nucleus and contains one SH2 domain and one S1 domain. SUPT6H participates in both DRB (5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole)-mediated transcriptional inhibition as well as the enhancement of transcriptional elongation by the RNA polymerase II (Pol II). SUPT6H interacts with the nuclear proteins SPT4 and SPT5, which comprise the DSIF (DRB-sensitivity-inducing factor) complex that binds RNA polymerase II, and ly regulates elongation. Via its C-terminus, SUPT6H can also interact with Histone H3. Due to alternative splicing events, three isoforms exist for SUPT6H. This antibody specifically recognizes the 230kd phosphorylated SUPT6H protein.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCross reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eQuantitative and spatial profiling: expression patterns are increasingly studied across cell states using multiplex imaging and omics-informed validation.\u003c\/li\u003e \u003cli\u003eIsoforms and post-translational modifications: researchers often evaluate how isoform composition and PTMs can shift apparent molecular weight or localization.\u003c\/li\u003e \u003cli\u003eContext-aware interpretation: comparative studies commonly include perturbations (stimulation, inhibition, genetic models) to relate target changes to pathway behavior.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blot (WB):\u003c\/strong\u003e compare relative target abundance and apparent size shifts (e.g., isoforms\/PTMs) across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry (IHC):\u003c\/strong\u003e assess distribution across tissue compartments and compare staining patterns between groups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence \/ ICC:\u003c\/strong\u003e evaluate subcellular localization and co-localization with compartment markers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and compare shifts after stimulation or differentiation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAcross these uses, researchers typically interpret changes in signal as relative differences between matched sample groups, considering sample preparation and biological context.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eApparent molecular weight can vary due to isoforms, proteolysis, glycosylation, phosphorylation, and sample preparation differences.\u003c\/li\u003e \u003cli\u003eSpecies reactivity and epitope conservation can influence observed signal patterns, especially in cross-species studies.\u003c\/li\u003e \u003cli\u003eControl concepts: include appropriate negative controls (e.g., isotype controls where relevant) and, when feasible, genetic or orthogonal controls (KO\/KD, peptide competition, or independent assays) to support interpretation.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eFor antibody reagents, monoclonal antibodies are often chosen for epitope consistency across lots, while polyclonals may recognize multiple epitopes and can show different background characteristics depending on context.\u003c\/p\u003e \u003c!-- Sources (internal): -
