Thyroid hormone receptor-associated protein 4 (THRAP4), also known as TRAP100. is a component of the thyroid hormone receptor-associated protein (TRAP) complex, a multi-subunit coactivator that interacts with nuclear receptors and other transcription factors to regulate gene expression. Originally identified through its association with thyroid hormone receptors, THRAP4 is part of the larger Mediator complex, which bridges DNA-bound transcription factors and RNA polymerase II to facilitate transcriptional initiation and elongation.
Structurally, THRAP4 contains conserved domains critical for protein-protein interactions within the Mediator complex. It plays a role in modulating transcriptional activation by mediating communication between regulatory proteins and the basal transcriptional machinery. Beyond thyroid hormone signaling, THRAP4 is implicated in diverse cellular processes, including metabolism, cell cycle regulation, and stress responses. Studies suggest its involvement in diseases such as cancer, where altered Mediator complex activity can drive oncogenic gene expression profiles.
Research on THRAP4 remains ongoing, with investigations focusing on its molecular interactions, post-translational modifications, and tissue-specific functions. Its ubiquitous expression and integration into fundamental transcriptional mechanisms highlight its importance in cellular homeostasis and disease pathogenesis.
