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 (PubMed:10406464, PubMed:11867769, PubMed:12037571, PubMed:12218053, PubMed:12556447, PubMed:14636573, PubMed:15340084, PubMed:15471764, PubMed:15989967, PubMed:16574658, PubMed:9653119). Acts as a coactivator for GATA1-mediated transcriptional activation during erythroid differentiation of K562 erythroleukemia cells (PubMed:24245781).

Sequence similarities

Belongs to the Mediator complex subunit 1 family.

Post-translational modifications

Phosphorylated by MAPK1 or MAPK3 during G2/M phase which may enhance protein stability and promote entry into the nucleolus (PubMed:16314496). Phosphorylation increases its interaction with PSIP1 (PubMed:29997176).

Activity summary

TRAP220 also known as MED1 is a protein with a molecular mass of approximately 220 kDa. It plays an important role as a component of the mediator complex which is important for transcription regulation. The expression of TRAP220/MED1 is found in various tissues with higher levels observed in liver lung and heart tissues. This protein acts mechanistically as a bridge between gene-specific transcription factors and RNA polymerase II facilitating the assembly of the pre-initiation complex.

Biological function summary

TRAP220/MED1 functions within the larger mediator complex a multi-protein coactivator essential for gene transcription by RNA polymerase II. It plays an important role in nuclear receptor signaling facilitating the transcriptional activation by various nuclear hormone receptors. MED1 interacts directly with these receptors through its various domains allowing the transcription of target genes responsive to hormonal signals.

Pathways

TRAP220/MED1 contributes significantly to transcriptional activation pathways involving nuclear receptors such as the PPAR (Peroxisome Proliferator-Activated Receptor) and thyroid hormone receptor pathways. It closely interacts with other proteins in these pathways including MED12 and MED14 which form integral parts of the mediator complex's function. Its involvement in these pathways highlights its critical role in lipid metabolism and energy homeostasis.

Associated diseases and disorders

TRAP220/MED1 is associated with metabolic and proliferative diseases. Its altered expression or mutations can lead to conditions such as obesity and cancer. For instance aberrant MED1 activity or expression levels have connections to breast cancer development through its role in estrogen receptor-mediated gene expression. This correlation emphasizes the protein's potential impact in various pathophysiological contexts driving ongoing research into MED1 as a therapeutic target.
