CREB (cyclic AMP response element-binding protein) is a stimulus-induced transcription factor that plays pivotal roles in cell survival and proliferation. The transactivation function of CREB is primarily regulated through Ser-133 phosphorylation by cAMP-dependent protein kinase A (PKA) and related kinases. Here we found that homeodomain-interacting protein kinase 2 (HIPK2), a DNA-damage responsive nuclear kinase, is a new CREB kinase for phosphorylation at Ser-271 but not Ser-133, and activates CREB transactivation function including brain-derived neurotrophic factor (BDNF) mRNA expression. Ser-271 to Glu-271 substitution potentiated the CREB transactivation function. ChIP assays in SH-SY5Y neuroblastoma cells demonstrated that CREB Ser-271 phosphorylation by HIPK2 increased recruitment of a transcriptional coactivator CBP (CREB binding protein) without modulation of CREB binding to the BDNF CRE sequence. HIPK2−/− MEF cells were more susceptible to apoptosis induced by etoposide, a DNA-damaging agent, than HIPK2+/+ cells. Etoposide activated CRE-dependent transcription in HIPK2+/+ MEF cells but not in HIPK2−/− cells. HIPK2 knockdown in SH-SY5Y cells decreased etoposide-induced BDNF mRNA expression. These results demonstrate that HIPK2 is a new CREB kinase that regulates CREB-dependent transcription in genotoxic stress.

Autophagy is a conserved cellular degradative process important for cellular homoeostasis and survival. An early committal step during the initiation of autophagy requires the actions of a protein kinase called ATG1 (autophagy gene 1). In mammalian cells, ATG1 is represented by ULK1 (uncoordinated-51-like kinase 1), which relies on its essential regulatory cofactors mATG13, FIP200 (focal adhesion kinase family-interacting protein 200 kDa) and ATG101. Much evidence indicates that mTORC1 [mechanistic (also known as mammalian) target of rapamycin complex 1] signals downstream to the ULK1 complex to negatively regulate autophagy. In this chapter, we discuss our understanding on how the mTORC1–ULK1 signalling axis drives the initial steps of autophagy induction. We conclude with a summary of our growing appreciation of the additional cellular pathways that interconnect with the core mTORC1–ULK1 signalling module.
