Qualitatively different effects were observed for the IL-1 -induced activation of stress-activated protein (SAP) kinases : permanent overexpression of IRAK did not affect the dose dependence but prolonged the kinetics of IL-1 -induced activation of SAP kinases , suggesting that this signaling branch may be regulated by distinct mechanisms.
 protein: IL-1; protein: stress-activated protein (SAP) kinases; protein: IRAK; protein: IL-1; protein: SAP kinases
