In mammalian cells, transcription is regulated in part by high molecular weight coactivating complexes that mediate signals between transcriptional activators and RNA polymerase II (Pol II).
The Mediator complex is one such multiprotein structure that functions as a bridge between regulatory proteins and Pol II, thereby regulating Pol II-dependent transcription.
Med28 (mediator complex subunit 28), also known as EG1 (endothelial-derived protein 1), magicin (merlin and Grb2-interacting cytoskeletal protein) or tumor angiogenesis marker EG-1, is a 178aa subunit of the Mediator complex that localizes to both nucleus and cytoplasm.
Widely expressed with highest expression in vascular tissues such as placenta, testis and liver, Med28 participates in the regulation of Pol II-mediated gene expression and is thought to play a key role in signal regulation and cell proliferation.
It is suggested that Med28 functions as a repressor of SMC (smooth muscle cell) differentiation and may be associated with abnormalities in SMC growth and differentiation, including atherosclerosis, asthma, hypertension and smooth muscle tumors.
