The THAP domain of THAP1 is a large C2CH module with zinc-dependent sequence-specific DNA-binding activity.

ABSTRACT: We have recently described an evolutionarily conserved protein motif, designated the THAP domain, which defines a previously uncharacterized family of cellular factors (THAP proteins). The THAP domain exhibits similarities to the site-specific DNA-binding domain of Drosophila P element transposase, including a putative metal-coordinating C2CH signature (CX(2-4)CX(35-53)CX(2)H). In this article, we report a comprehensive list of approximately 100 distinct THAP proteins in model animal organisms, including human nuclear proapoptotic factors THAP1 and DAP4/THAP0, transcriptional repressor THAP7, zebrafish orthologue of cell cycle regulator E2F6, and Caenorhabditis elegans chromatin-associated protein HIM-17 and cell-cycle regulators LIN-36 and LIN-15B. In addition, we demonstrate the biochemi
