Protein attributes

Sequence length	337 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors By similarity.
Subunit structure	Component of the Mediator complex By similarity.
Subcellular location	Nucleus Probable.
Sequence similarities	Belongs to the Mediator complex subunit 19 family.
