== 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.<ref name="entrez" />

== Interactions ==

MED22 has been shown to interact with MED30.<ref name=pmid12584197>{{cite journal | vauthors = Sato S, Tomomori-Sato C, Banks CA, Sorokina I, Parmely TJ, Kong SE, Jin J, Cai Y, Lane WS, Brower CS, Conaway RC, Conaway JW | title = Identification of mammalian Mediator subunits with similarities to yeast Mediator subunits Srb5, Srb6, Med11, and Rox3 | journal = The Journal of Biological Chemistry | volume = 278 | issue = 17 | pages = 15123–7 | date = Apr 2003 | pmid = 12584197 | doi = 10.1074/jbc.C300054200 | doi-access = free }}</ref>
