NCBI Protein Information
Integrase-type DNA-binding superfamily protein
NCBI Summary
WRINKLED1 encodes transcription factor of the AP2/ERWEBP class. Protein has two plant-specific (AP2/EREB) DNA-binding domains and is involved in the control of storage compound biosynthesis in Arabidopsis. Mutants have wrinkled seed phenotype, due to a defect in the incorporation of sucrose and glucose into triacylglycerols. Transgenic sGsL plants (21-day-old) grown on 6% sucrose for 24 hours had 2-fold increase in levels of expressions (sGsL line carries a single copy of T-DNA containing the Spomin::GUS-Spomin::LUC dual reporter genes in the upper arm of chromosome 5 of ecotype Col-0. The sporamin .minimal. promoter directs sugar-inducible expression of the LUC and GUS reporters in leaves). Regulation by LEC2 promotes fatty acid accumulation during seed maturation.

UniProt Comments
May be involved in the regulation of gene expression by stress factors and by components of stress signal transduction pathways . Transcriptional activator involved in the activation of a subset of sugar-responsive genes and the control of carbon flow from sucrose import to oil accumulation in developing seeds. Binds to the GCC-box pathogenesis-related promoter element. Promotes sugar uptake and seed oil accumulation by glycolysis. Required for embryo development, seed germination and, indirectly, for seedling establishment. Negative regulator of the ABA-mediated germination inhibition.
