Model of LPS-mediated IRAK2-dependent post-transcriptional control.
Upon LPS stimulation in macrophages, IRAK4 is activated, leading to the
modification and activation of IRAK1 and IRAK2. While IRAK1 and IRAK2 activate
TAK1 and MEKK3 to mediate NFκB activation, the activated IRAK2 recruits
kinases (MKK3/6, ERK, p38, MK2, and MNK1) and effector molecules (TRAF6,
eIF4E, and TTP) to mediate mRNA stabilization and translation initiation.
