Zinc finger THAP-type profile





Description

The THAP-type zinc finger (consensus: C-x(2,4)-C-x(35,50)-C-x(2)-H) is an ~90-residue domain restricted to animals, which is shared between the THAP family of cellular DNA-binding proteins, and transposases from mobile genomic parasites [1,2]. THAP1, the prototype of the THAP family, possesses zinc-dependent sequence-specific DNA binding activity and recognizes a consensus DNA target sequence of 11 nucleotides [3]. The THAP-type zinc finger can be found in one or more copies and can be associated with other domains, such as the C2H2-type zinc finger (see <PDOC00028>).

The structure of the THAP-type zinc finger (see <PDB:2JTG>) reveals the presence between the C2CH zinc coordinating residues of a short antiparallel β-sheet interspersed by a long loop-helix-loop insertion. This loop-helix-loop motif has been shown to be essential for the identification of a number of critical residues for DNA recognition [4].

Some proteins known to contain a THAP-type zinc finger are listed below:

  • Mammalian Thanatos-associated protein-1 (THAP1). It potentiates both serum withdrawal- and tumor necrosis factor α-induced apoptosis, and interacts with prostate-apoptosis-response 4 (Par4), a well-characterized proapoptotic factor.
  • Mammalian death-associated protein DAP4/p52rIPK or THAP0. It has been identified in a genetic screen for genes involved in interferon-γ- induced apoptosis in HeLa cells and in a two-hybrid screen for indirect activators of the interferon-induced kinase PKR, an important mediator of stress-induced apoptosis.
  • Mammalian THAP2 to THAP11.
  • Drosophila melanogaster dorsal interacting protein 2 (DIP2).
  • Drosophila melanogaster P element transposase.

The profile we developed covers the whole THAP-type zinc finger with 4 positions upstream, and about 20 positions downstream.
