Mediator of RNA polymerase II transcription subunit 22 is an enzyme that in humans is encoded by the MED22 gene.[5][6][7]

Function

This gene is located in the surfeit gene cluster, a group of very tightly linked housekeeping genes that do not share sequence similarity. The gene is oriented in a head-to-head fashion with RPL7A (SURF3) and the two genes share a bidirectional promoter. The encoded proteins are localized to the cytoplasm. Two alternative transcript variants encoding different isoforms have been identified for this gene.[7]

Interactions

MED22 has been shown to interact with MED30.[8]

Model organisms

Model organisms have been used in the study of MED22 function. A conditional knockout mouse line called Med22^{tm1a(EUCOMM)Wtsi} was generated at the Wellcome Trust Sanger Institute.[9] Male and female animals underwent a standardized phenotypic screen[10] to determine the effects of deletion.[11][12][13][14] Additional screens performed: - In-depth immunological phenotyping[15]
