Beschreibung:
Plants constantly monitor their light environment in order to grow and develop optimally, in part through use of the phytochromes, which sense red/far-red light. A phytochrome binding protein, PKS1 (phytochrome kinase substrate 1), was identified that is a substrate for light-regulated phytochrome kinase activity in vitro. In vivo experiments suggest that PKS1 is phosphorylated in a phytochrome-dependent manner and negatively regulates phytochrome signaling. The data suggest that phytochromes signal by serine-threonine phosphorylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fankhauser, C -- Yeh, K C -- Lagarias, J C -- Zhang, H -- Elich, T D -- Chory, J -- R01GM52413/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1999 May 28;284(5419):1539-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plant Biology Laboratory, Howard Hughes Medical Institute, Salk Institute, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10348744" target="_blank"〉PubMed〈/a〉
