AT hook motif DNA-binding family protein [Arabidopsis thaliana]

Protein Classification

PPC domain-containing DNA-binding protein( domain architecture ID 10507306)

plants and prokaryotes conserved (PPC) domain-containing DNA-binding protein similar to plant AT-hook motif nuclear-localized (AHL) proteins, which act as transcription factors that specifically bind AT-rich DNA sequences related to the nuclear matrix attachment regions (MARs)

Plants and Prokaryotes Conserved (PCC) domain; This is a Plants and Prokaryotes Conserved (PPC) domain found in proteins that contain AT-hook motifs pfam02178 which strongly suggests a DNA-binding function for the proteins as a whole. Proteins with PPC domains are found in Bacteria, Archaea and the plant kingdom.The PPC domain has a single alpha-helix packed against an antiparallel beta-sheet, which is formed by five beta-strands. There are three highly conserved histidine residues, eg at 117, 119 and 133 in Swiss:Q46QL5 which appear to form a zinc-binding site, and the domain has been observed to form homotrimers. The domain co-occurs with a thioredoxin-like domain in uncharacterized cyanobacterial proteins.
