Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E. coli-derived human MED4 recombinant protein (Position: R27-K140). (reported region: R27-K140).
- Molecular weight context: reported MW: 34 kDa; calculated MW: nan
- Reactivity: Human,Mouse,Rat
- Applications: ELISA, IHC, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
Mediator of RNA polymerase II transcription subunit 4, also known as mediator complex subunit 4 (MED4), a component of Mediator or vitamin D3 receptor-interacting protein complex 36 kDa component (DRIP36), is a protein that in humans is encoded by the MED4 gene. The Mediator complex interacts with DNA-binding gene-specific transcription factors to modulate transcription by RNA polymerase II. The MED4 gene was mapped to chromosome 13 based on sequence similarity between the MED4 sequence and a genomic contig. Functional note: Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. 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. Reported localization: Nucleus.
Research relevance and current trends
- Epigenetics and Nuclear Signaling: Researchers commonly examine how MED4 relates to this theme using model systems and orthogonal readouts.
- Mediator Complex: Researchers commonly examine how MED4 relates to this theme using model systems and orthogonal readouts.
- Pol II Transcription: Researchers commonly examine how MED4 relates to this theme using model systems and orthogonal readouts.
Common research applications
- Western blotting: compare relative MED4 levels across conditions; band patterns may reflect isoforms and processing.
- IHC/IHC-F: assess spatial distribution of MED4 across tissue regions and cell types using matched controls.
- ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
