WebDec 1, 2011 · Mkk1 and Mkk2 are subject to retrophosphorylation by Mpk1, which appears to be a negative feedback regulatory mechanism and requires a D motif in the MEKs (Jimenez-Sanchez et al. 2007). Loss of function of any protein kinase below Pkc1 (or both Mkk1 and Mkk2) results in cell lysis at 37°. Webcompared to CheY1 and CheY2. Furthermore, our data indicate retrophosphorylation of CheAY2 by CheY1~P, suggesting a role of CheY2 as a phosphate sink to modulate the …
Retrophosphorylation of Mkk1 and Mkk2 MAPKKs by the Slt2 …
WebMutation or deletion of a conserved MAPK-docking site at the N-terminal extension of Mkk2 precluded its interaction with Slt2 and negatively affected retrophosphorylation. Our data show that the cell wall integrity MAPKKs are targets for their downstream MAPK, suggesting the existence of complex feedback regulatory mechanisms at this level. WebUp to now, this retrophosphorylation as a new mechanism of adaptation is not fully understood. The striking differences in the two dephosphorylation reactions of the two … hersendarmas
