• PubMed Abstract: 
  

Mitogen-activated protein (MAP) kinases mediate the cellular response to stimuli such as pro-inflammatory cytokines and environmental stress. P38gamma is a new member of the MAP kinase family, and is expressed at its highest levels in skeletal muscle. P38gamma is 63% identical in sequence to P38alpha. The structure of P38alpha MAP kinase has been determined in the apo, unphosphorylated, inactive form. The structures of apo unphosphorylated ERK2, a related MAP kinase, and apo phosphorylated ERK2 have also been determined.
