Strong NF-κB activation requires ligation of both the CD28 coreceptor and TCR. Phosphoinositide-dependent kinase 1 (PDK1) acts as a scaffold by binding both protein kinase Cθ (PKCθ) and CARMA1, and is therefore essential for signaling to NF-κB. In this article

The AMP-activated protein kinase (AMPK) regulates metabolism in normal and pathological conditions and responds to nutrients, hormones, anti-diabetic drugs and physical exercise. AMPK is activated by the kinase LKB1 and inactivated by phosphatases whose identities remain uncertain. Here we show

A T-box-containing protein expressed in T cells (T-bet) is a key transcription factor involved in the regulation of Th cell differentiation. Although T-bet-deficient CD4(+) T cells fail to produce IFN-γ and typically differentiate into Th2 cells in vitro, ectopic overexpression

CREB binding protein (CBP) is an acetyltransferase that plays an important role in many biological processes. Here, we show that Akt phosphorylates CBP at threonine 1871 and suppresses its acetyltransferase activity by impeding the binding of CBP to histone H3

HIPK2 (homeodomain-interacting protein kinase-2) binds to and phosphorylates, at Ser and Thr residues, a large number of targets involved in cell division and cell fate decision in response to different physiological or stress stimuli. Inactivation of HIPK2 has been observed
