Photoreceptor2
  • Phototropin is not the only blue light photoreceptor. (oup.com)
  • The photoreceptor involved is called Phot1 (Phototropin 1) or JK244 . (stackexchange.com)
Cryptochrome1
  • We describe extensive use of histidine kinase-based two-component systems and tyrosine kinase signaling, the presence of bacterial and plant type photoreceptors (phytochromes, cryptochrome, and phototropin) and of plant-type pentatricopeptide repeat proteins, as well as metabolic pathways, and a cell cycle control system typically found in more complex eukaryotes. (duke.edu)
Photoreceptors1
  • Another topic is focused on the funtional analysis of the photoreceptors channelrhodopsin 1 and phototropin. (fau.de)
Stomatal1
  • It is interesting to note that the two phenotypes rescued by chloroplast-bound phot2 (stomatal opening and chloroplast-avoidance) are also the two phototropin-mediated responses that are independent of the signalling partner NPH3 (Christie et al. (plantae.org)
Inhibition2
  • LOV2 acts as an inhibitor of phototropin kinase in the dark, and light cancels the inhibition through cysteine-FMN adduct formation. (or.jp)
  • On illumination this phototropin, through currently unknown messengers, causes inhibition of polar Auxin transport in the illuminated side. (stackexchange.com)
Chloroplast1
  • In the UV (A) and blue range, phototropin induces plant movement and governs cell chloroplast movement. (boyagrowlight.com)
Responses2
  • After confirming that these proteins were indeed restricted to the correct subcellular location, the authors analysed which phototropin-dependent responses were rescued in these lines. (plantae.org)
  • The binding of a 14-3-3 protein to Vfphot was found in etiolated seedlings and leaves in response to BL, suggesting that this event was common to phototropin-mediated responses. (elsevierpure.com)
Protein1
  • While the function of the LOV2 domain in the context of the phototropin protein is not fully elucidated, its thorough biophysical characterization as an isolated domain has created a strong foundation for engineering of photoswitches. (optobase.org)
Proteins1
  • We engineered a photoactivatable system for rapidly and reversibly exporting proteins from the nucleus by embedding a nuclear export signal in the LOV2 domain from phototropin 1. (optobase.org)
Blue light3
  • Phototropin is also required for blue light mediated transcript destabilization of specific mRNAs in the cell. (wikipedia.org)
  • 2008) Blue light-induced autophoshporylation of phototropin is a primary step for signaling. (nagoya-u.ac.jp)
  • In the process of evolution, plants acquired phytochrome , which mainly receives light in the red light region, and multiple blue light receptors , including his lyptochrome and phototropin, in order to sense the light environment. (vanqled.com)
Domain1
  • We focus on the well-characterized light-oxygen-voltage 2 (LOV2) domain from Avena sativa phototropin 1 as our cornerstone for design. (optobase.org)
