Histidine kinases in signal transduction pathways of eukaryotes.
Autophosphorylating histidine kinases are an ancient conserved family of enzymes that are found in eubacteria, archaebacteria and eukaryotes. They are activated by a wide range of extracellular signals and transfer phosphate moieties to aspartates found in response regulators. Recent studies have shown that such two-component signal transduction pathways mediate osmoregulation in Saccharomyces ...
متن کاملSignal transduction: Gyrating protein kinases
Recently determined structures have linked histidine kinases with class II topoisomerases, the DNA repair enzyme MutL and the molecular chaperone Hsp90. This surprising finding may foreshadow a shift in our understanding of energy coupling mechanisms in signal transduction networks.
متن کاملStimulus perception in bacterial signal-transducing histidine kinases.
Two-component signal-transducing systems are ubiquitously distributed communication interfaces in bacteria. They consist of a histidine kinase that senses a specific environmental stimulus and a cognate response regulator that mediates the cellular response, mostly through differential expression of target genes. Histidine kinases are typically transmembrane proteins harboring at least two doma...
متن کاملCa2+-dependent protein kinases and stress signal transduction in plants.
Stress responses in plants involve changes in the transcription of specific genes. The constitutively active mutants of two related Ca2+-dependent protein kinases (CDPK1 and CDPK1a) activate a stress-inducible promoter, bypassing stress signals. Six other plant protein kinases, including two distinct CDPKs, fail to mimic this stress signaling. The activation is abolished by a CDPK1 mutation in ...
متن کاملCrosstalk between Photoreceptor and Sugar Signaling Modulates Floral Signal Transduction
Over the past decade, integrated genetic, cellular, proteomic and genomic approaches have begun to unravel the surprisingly crosstalk between photoreceptors and sugar signaling in regulation of floral signal transduction. Although a number of physiological factors in the pathway have been identified, the molecular genetic interactions of some components are less well understood. The further elu...
