 15-74 6.43e-19

TBPIP/Hop2 winged helix domain; This family consists of several eukaryotic TBP-1 interacting protein (TBPIP) sequences. TBP-1 has been demonstrated to interact with the human immunodeficiency virus type 1 (HIV-1) viral protein Tat, then modulate the essential replication process of HIV. In addition, TBP-1 has been shown to be a component of the 26S proteasome, a basic multiprotein complex that degrades ubiquitinated proteins in an ATP-dependent fashion. Human TBPIP interacts with human TBP-1 then modulates the inhibitory action of human TBP-1 on HIV-Tat-mediated transactivation. TBPIP was found to be an activator that specifically stimulates the homologous pairing catalyzed by DMC1. Family members also include yeast homologous-pairing protein 2 (Hop2) and its homologs from animals and plants. They are required for proper homologous pairing and efficient cross-over and intragenic recombination during meiosis.

 142-198 2.55e-15

Leucine zipper with capping helix domain; This domain is found at the C-terminal region of Hop2 and Mnd1 proteins. In meiotic DNA recombination, the Hop2-Mnd1 complex promotes Dmc1-mediated single-stranded DNA (ssDNA) invasion into homologous chromosomes to form a synaptic complex. Hop2 (for homologous pairing; also known as TBPIP) is expressed specifically during meiosis, same as Mnd1 (for meiotic nuclear divisions 1). The C-terminal region of both Hop2 and Mnd1, folds into three alpha-helices that are interrupted by two short non-helical regions. These alpha-helices of the two proteins together form a parallel coiled coil that provides the major interface for heterodimer formation. The non-helical regions form substantially kinked junctions between adjacent leucine zippers: the LZ1-LZ2 and LZ2-LZ3 junctions.This domain is the C-terminal segment of Hop2 and Mnd1 which folds back onto the C-terminal leucine zipper (LZ3) to form a helical bundle-like structure, hence designated LZ3wCH (for LZ3 with capping helices). The LZ3wCH region plays a role in interacting with the Dmc1 nucleofilament.

 15-72 1.60e-03

Ferric uptake regulator(Fur) and related metalloregulatory proteins; typically iron-dependent, DNA-binding repressors and activators; Ferric uptake regulator (Fur) and related metalloregulatory proteins are iron-dependent, DNA-binding repressors and activators mainly involved in iron metabolism. A general model for Fur repression under iron-rich conditions is that activated Fur (a dimer having one Fe2+ coordinated per monomer) binds to specific DNA sequences (Fur boxes) in the promoter region of iron-responsive genes, hindering access of RNA polymerase, and repressing transcription. Positive regulation by Fur can be direct or indirect, as in the Fur repression of an anti-sense regulatory small RNA. Some members sense metal ions other than Fe2+. For example, the zinc uptake regulator (Zur) responds to Zn2+, the manganese uptake regulator (Mur) responds to Mn2+, and the nickel uptake regulator (Nur) responds to Ni2+. Other members sense signals other than metal ions. For example, PerR, a metal-dependent sensor of hydrogen peroxide. PerR regulates DNA-binding activity through metal-based protein oxidation, and co-ordinates Mn2+ or Fe2+ at its regulatory site. Fur family proteins contain an N-terminal winged-helix DNA-binding domain followed by a dimerization domain; this CD spans both those domains.
