Protein
AT-hook motif nuclear-localized protein 22
Organism
Arabidopsis thaliana
Function
Transcription factor that specifically binds AT-rich DNA sequences related to the nuclear matrix attachment regions (MARs). Binds an AT-rich DNA sequences in the FLOWERING LOCUS T (FT) promoter (PubMed:22442143). Acts redundantly with AHL18, AHL27 and AHL29 in the regulation of flowering and regulation of the hypocotyl elongation. Plays a role in both photo- and skotomorphogenesis (PubMed:19517252). Acts as a chromatin remodeling factor that modifies the architecture of FLOWERING LOCUS T (FT) chromatin by modulating both H3 acetylation and methylation leading to the regulation of FT expression during flowering induction (PubMed:22442143).
