In other words, Mediator acts as a centralized hub or integrator for transcriptional regulation (reviewed in 1,2). Multiple studies have shown that Mediator functions include epigenetic regulation, transcriptional elongation, transcription termination, mRNA processing, non-coding RNA activation, and super-enhancer formation. Through these functions, Mediator contributes to the regulation of many biological processes, including insulin signaling (3), NF-κB-dependent signaling (4), stem cell pluripotency and self-renewal (5,6), and proliferation of colon cancer cells (7,8). The Mediator complex consists of 31 protein subunits and can be divided into four distinct modules: the head, middle, tail, and CDK8 kinase module. The CDK8 kinase module contains the CDK8, cyclin C, MED12, and MED13 subunits and is thought to act as a molecular switch, phosphorylating the C-terminal domain (CTD) of Rpb1, the large subunit of Pol II, to inhibit Pol II recruitment and transcription initiation (9,10).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nActivator-recruited cofactor 250 kDa component; ARC250; DRIP250; HSPC221; KIAA0593; MED13; Mediator complex subunit 13; Mediator of RNA polymerase II transcription subunit 13; mediator of RNA polymerase II transcription, subunit 13 homolog; MRD61; THRAP1; thyroid hormone receptor associated protein 1; Thyroid hormone receptor-associated protein 1; Thyroid hormone receptor-associated protein complex 240 kDa component; thyroid hormone receptor-associated protein complex component TRAP240; thyroid hormone receptor-associated protein, 240 kDa subunit; TRAP240; Vitamin D3 receptor-interacting protein complex component DRIP250\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 230\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800008478889,"sku":"91684S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-91684s","provider":"Iright","version":"1.0","type":"link"}
