WHY1

Gene
WHY1
Protein
Single-stranded DNA-binding protein WHY1, chloroplastic
Organism
Solanum tuberosum
Length
274 amino acids
Function
Single-stranded DNA-binding protein that acts as a transcriptional activator of the pathogenesis-related gene PR-10a. Upon elicitation, binds a 30bp promoter sequence known as elicitor element response (ERE) and is required for PR-10a expression.
Similarity
Belongs to the Whirly family.

Protein
Single-stranded DNA-binding protein WHY1, chloroplastic
Organism
Zea mays
Length
266 amino acids
Function
Single-stranded DNA and RNA binding protein that maintains plastid genome stability by preventing break-induced and short homology-dependent illegitimate recombinations. Functions in RNA metabolism and is involved in the maturation of the atpF and 23S ribosomal RNAs.
Similarity
Belongs to the Whirly family.

Gene

Protein
Single-stranded DNA-binding protein WHY1, chloroplastic
Organism
Arabidopsis thaliana
Length
263 amino acids
Function
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.
Similarity
Belongs to the Whirly family.
