Histidine kinase receptor
WebbHistidine kinases are typically transmembrane proteins harboring at least two domains: an input (or sensor) domain and a cytoplasmic transmitter (or kinase) domain. They can be identified and classified by virtue of their conserved cytoplasmic kinase domains.

Webb26 feb. 2024 · Aside from notable exceptions ( 10, 11 ), HKs are canonically viewed as dimeric proteins with modular architecture that includes an extracytoplasmic sensor region, transmembrane (TM) helices, various signal transduction domains, and a kinase domain consisting of dimerization and histidine phosphotransfer (DHp) and catalytic ATP … WebbHistidine-kinase-associated receptorsactivate a “two-component” signaling pathway in which the kinase phosphorylates itself on histidine and then immediately transfers the phosphate to a second intracellular …
Webb15 sep. 2001 · Common histidine-to-aspartate (His→Asp) phosphorelay is a paradigm of signal transduction in both prokaryotes and eukaryotes for the propagation of certain environmental stimuli, in which histidine (His)-kinases play central roles as sensors for environmental signals. WebbFMS-like tyrosine kinase 3 (FLT3) gene encodes for a receptor tyrosine kinase ... . 21,32,33 The most common point mutations in FLT3-TKD are substitution of aspartic acid of TKD2 with tyrosine or histidine at residue 835 and substitution of asparagine or phenylalanine of TKD1 at residues of 676 and 691, ...
Webb8 nov. 1996 · The simplest explanation of the cki1 phenotype is that CKI1, acting as a cytokinin receptor, when overexpressed confers the ability on the expressing cells to sense low concentrations of endogenous cytokinin that is normally unable to trigger growth and shoot formation. WebbHistidine kinases (HK) are multifunctional, typically transmembrane, proteins of the transferase class of enzymes that play a role in signal transduction across the cellular membrane. The vast majority of HKs are homodimers that exhibit autokinase, phosphotransfer, and phosphatase activity.
