Gene: MED12 (mediator complex subunit 12) Homo sapiens
Symbol: MED12
Name: mediator complex subunit 12
Description: Exhibits several functions, including protein C-terminus binding activity; thyroid hormone receptor binding activity; and transcription coactivator activity. Involved in positive regulation of transcription by RNA polymerase II and transcription initiation from RNA polymerase II promoter. Localizes to mediator complex. Implicated in FG syndrome; leiomyosarcoma; mental depression; and syndromic X-linked intellectual disability.
Type: protein-coding
RefSeq Status: REVIEWED
