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). Component of the Mediator complex. Belongs to the Mediator complex subunit 16 family. The predicted gene PICST_61313 has been split into 2 genes: PICST_61313 and PICST_48926. The predicted gene PICST_61313 has been split into 2 genes: PICST_61313 and PICST_48926.
