Western blot - Anti-MED12 antibody [BLR084G] (AB275962)

Western blot : Anti-MED12 antibody [BLR084G] (ab275962) staining at 1/1000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab275962 was shown to bind specifically to MED12. A band was observed at 238-243 kDa in wild-type HCT 116 cell lysates with no signal observed at this size in MED12 knockout cell line. To generate this image, wild-type and MED12 knockout HCT 116 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 5 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Supplementary information

MED12 also known as mediator complex subunit 12 is a component of the transcriptional Mediator complex. It weighs approximately 250 kDa and is widely expressed in many tissues showing high transcriptional regulatory activity. MED12 collaborates with other subunits within the Mediator complex to transmit signals from regulatory DNA elements to RNA polymerase II facilitating gene expression regulation.
Biological function summary

MED12 functions as a core component of the larger Mediator complex which plays an important role in controlling RNA polymerase II-dependent genes. Through interactions with activators and repressors MED12 participates in chromatin modification and looping affecting gene transcription rates. It is enriched in tissues where fine control of gene expression is essential impacting growth differentiation and development processes.

Pathways

MED12 integrates into critical signaling pathways including the Wnt/β-catenin and Hedgehog pathways. In these pathways MED12 interacts with other proteins like β-catenin serving as a connecting node that influences the transcription of target genes essential for cell proliferation and differentiation. Such interactions help coordinate cellular responses to external signals and ensure proper pathway regulation.

MED12 mutations have been linked to disorders like Lujan-Fryns syndrome and uterine leiomyomas. In these contexts MED12 interacts with G protein-coupled receptors and other transcription factors such as β-catenin resulting in dysregulation that leads to the development of these conditions. Understanding the connections between MED12 and associated proteins provides insights into the underlying mechanisms of these pathologies.

Target data

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 direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional pre-initiation complex with RNA polymerase II and the general transcription factors. This subunit may specifically regulate transcription of targets of the Wnt signaling pathway and SHH signaling pathway.
