Host Species Human
Synonym SRB7, SURB7, Mediator complex subunit 21, RNA polymerase II holoenzyme component SRB7, hSrb7.
Background Mediator Complex Subunit 21 (MED21) belongs to the mediator complex subunit 21 family. MED21 interacts with the human RNA polymerase II holoenzyme and is participated in transcriptional regulation of RNA polymerase II transcribed genes. A pseudogene of MED21 can be found on chromosome 8. Alternative splicing results in multiple transcript variants.
Description MED21 Human Recombinant expressed in E.Coli is a single, non-glycosylated polypeptide chain containing 167a.a. (1-144 a.a.) and having a molecular weight of 18.0kDa.MED21 is fused to a 23a.a. His-tag at N-terminus and purified by unique purification methods.
