UniProt Comments
Acts predominantly in the phot1 pathway. Involved in the leaf positioning and also in the phot2 pathway controlling the leaf flattening. Component of the network that modulates the very low-fluence response (VLFR) branch of phyA signaling. Regulates phytochrome-mediated photomorphogenesis and hypocotyl phototropism. May act by controlling auxin homeostasis.
