4eet is a 2 chain structure with sequence from Arabidopsis thaliana. The March 2015 RCSB PDB Molecule of the Month feature on Phototropin by David Goodsell is 10.2210/rcsb_pdb/mom_2015_3. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

PHOT2_ARATH Protein kinase that acts as a blue light photoreceptor in a signal-transduction pathway for photo-induced movements. Mediates calcium spiking of extra- and intracellular origins in response to blue light. Involved in hypocotyl phototropism. Contributes to the chloroplast accumulation in low blue light and mediates their translocation (avoidance response) at high fluence. Regulates stomata opening and photomorphogenesis response of leaf tissue. Not involved in hypocotyl elongation inhibition, anthocyanin accumulation or cotyledon opening.^[1] ^[2] ^[3] ^[4] ^[5]
