Novel Candidate Substrates of AMP-activated Protein Kinase Identified in Red Blood Cell Lysates

Biochem Biophys Res Commun. 2010 Jul 23;398(2):296-301. doi: 10.1016/j.bbrc.2010.06.084. Epub 2010 Jun 25.


AMPK is a metabolic stress-sensing kinase with important functions for red blood cell (RBC) survival. By using a proteomic approach, we identified putative AMPK targets in hemoglobin-depleted lysates of RBC, including metabolic enzymes, cytoskeletal proteins and enzymes involved in the oxidative stress response. These data tie in with the phenotypic observations of AMPKalpha1-deficient RBC and provide reference for future studies.
