Phosphosite mapping of P-type plasma membrane H+-ATPase in homologous and heterologous environments.
Frederiksberg, Denmark. In J Biol Chem, Mar 2012
After a mass spectrometric analysis of the resulting peptides we could identify 10 different phosphorylation sites in plasma membrane H(+)-ATPases AHA1, AHA2, AHA3, and AHA4/11, five of which have not been reported before, bringing the total number of phosphosites up to 11, which is substantially higher than reported so far for any other P-type ATPase.
Investigating the functions of the RIN4 protein complex during plant innate immune responses.
Davis, United States. In Plant Signal Behav, 2009
However, the molecular mechanisms by which RIN4 controls multiple immune responses have remained elusive. in our recently published study, we purified components of the RIN4 protein complex from A. thaliana and identified several novel RIN4-associated proteins.1 we found that one class of RIN4-associated proteins, the plasma membrane H(+)-ATPases AHA1 and AHA2, play a crucial role in resisting pathogen invasion.
