Crystal Structure of WHY1 from Arabidopsis thaliana
Template:ABSTRACT PUBMED 24192350
Function
[WHY1_ARATH] Single-stranded DNA-binding protein that functions in both chloroplasts and nucleus. In chloroplasts, maintains plastid genome stability by preventing break-induced and short homology-dependent illegitimate recombinations. In nucleus, modulates telomere length homeostasis by inhibiting the action of the telomerase at the extreme termini of chromosomes. Is recruited to a distal element upstream of the kinesin KP1 to mediate the transcriptional repression of KP1. Is required for full salicylic acid-dependent plant disease resistance responses. Can bind double-stranded DNA in vivo.[1] [2] [3] [4] [5] [6]
About this Structure
4koo is a 4 chain structure with sequence from Arath. Full crystallographic information is available from OCA.
