Function
Inhibits zinc finger homeodomain (ZHD) transcription factors, such as ZHD5, by interacting with them to prevent both their nuclear localization and their DNA-binding properties. Involved in integrating signals from multiple hormones by preventing the expression of genes involved in gibberellic acid (GA), auxin and brassinosteroid signaling and by promoting the expression of abscisic acid (ABA)-responsive genes. Regulates several development aspects, including photomorphogenesis, apical dominance, longevity, flower morphology and fertility, as well as root and stem elongation. Promotes the formation of ectopic shoot meristems on leaf margins.
