DBP1 DNA-binding protein phosphatase 1 [Arabidopsis thaliana (thale cress)] - Gene

Summary

Gene symbol: DBP1
Gene description: DNA-binding protein phosphatase 1
Primary source: Araport:AT2G25620
Locus tag: AT2G25620
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: AtDBP1; DNA-binding protein phosphatase 1
Summary: Encodes DBP1, a member of the DBP factors (DNA-binding protein phosphatases) featuring sequence-specific DNA-binding and protein phosphatase activity. DBP1 is involved in plant-potyvirus interactions. Loss-of-function of DBP1 renders resistance to potyviruses.
