== Function ==
[https://www.uniprot.org/uniprot/FRA1E_FRAAN FRA1E_FRAAN] Involved in the control of flavonoid biosynthesis in fruits, probably by binding directly to natural flavonoids (PubMed:19969523). Binds the natural flavonoid quercetin-3-O-glucuronide with affinities in the low micromolar range (PubMed:24133217).<ref>PMID:19969523</ref> <ref>PMID:24133217</ref>

== Publication Abstract from PubMed ==
The PR10 family protein Fra a 1E from strawberry (Fragaria x ananassa) is down-regulated in white strawberry mutants, and transient RNAi (RNA interference)-mediated silencing experiments confirmed that Fra a 1 is involved in fruit pigment synthesis. In the present study, we determined the solution structure of Fra a 1E. The protein fold is identical with that of other members of the PR10 protein family and consists of a seven-stranded antiparallel beta-sheet, two short V-shaped alpha-helices and a long C-terminal alpha-helix that encompass a hydrophobic pocket. Whereas Fra a 1E contains the glycine-rich loop that is highly conserved throughout the protein family, the volume of the hydrophobic pocket and the size of its entrance are much larger than expected. The three-dimensional structure may shed some light on its physiological function and may help to further understand the role of PR10 proteins in plants.
