    Summary
    Enables transcription coactivator activity. Involved in negative regulation of transcription by RNA polymerase II; positive regulation of transcription by RNA polymerase II; and positive regulation of transcription by galactose. Part of mediator complex. Human ortholog(s) of this gene implicated in FG syndrome; leiomyosarcoma; major depressive disorder; phobic disorder; and syndromic X-linked intellectual disorder Lujan-Fryns-type. Orthologous to human MED12 (mediator complex subunit 12) and MED12L (mediator complex subunit 12L). [provided by Alliance of Genome Resources, Dec 2024]
