Cdk5 is a member of the cyclin-dependent kinase family. Unlike other conventional Cdks that are major regulators of eukaryotic cell cycle progression, Cdk5 displays diverse functions in neuronal as well as non-neuronal tissues. In particular, accumulating evidence points to the roles of this kinase in CNS development and other cellular processes. In this article, we summarize the functional rol...
Cyclin-dependent kinase 5 (Cdk5) is a multifunctional neuronal protein kinase that is required for neurite outgrowth and cortical lamination and that plays an important role in dopaminergic signaling in the neostriatum through phosphorylation of Thr-75 of DARPP-32 (dopamine and cAMP-regulated phosphoprotein, molecular mass 32 kDa). Casein kinase 1 (CK1) has been implicated in a variety of cellu...
Cellular adhesion to the extracellular matrix is mediated by a diverse class of alpha/beta heterodimeric receptors known as integrins, which transduce signals to activate multiple intracellular signal transduction pathways within the cells. The signaling pathway linking integrins to mediate neuronal process outgrowth is not well understood. Here, we have provided evidence that intracellular sig...
Deregulated Cdk5 causes neurotoxic amyloid beta peptide (Aβ) processing and cell death, two hallmarks of Alzheimer's disease, through the Foxo3 transcriptional factor in hippocampal cells, primary neurons and an Alzheimer's disease mouse model. Using an innovative chemical genetic screen, we identified Foxo3 as a direct substrate of Cdk5 in brain lysates. Cdk5 directly phosphorylates Foxo3, whi...
Low voltage-activated (LVA) T-type Ca2+ channels activate in response to subthreshold membrane depolarizations and therefore represent an important source of Ca2+ influx near the resting membrane potential. In neurons, these proteins significantly contribute to control relevant physiological processes including neuronal excitability, pacemaking and post-inhibitory rebound burst firing. Three su...
Pituitary adenomas constitute 15-20% of intracranial neoplasms. Previously we reported that cyclin-dependent kinase 5 (CDK5) is upregulated in pituitary tumors associated with activating protein p35, and plays an essential role in pituitary adenomas progression. Here we explored the mechanisms of CDK5 signaling in prolactin pituitary adenomas. Our data indicate that p35 expression and CDK5 acti...
Cyclin-dependent kinase 5 (CDK5) has been documented in podocyte injuries in diabetic nephropathy (DN), however its role in renal tubular epithelial cells has not been elucidated. We report here that CDK5 is detrimental and promotes tubulointerstitial fibrosis (TIF) via the extracellular signal-regulated kinase 1/2 (ERK1/2)/peroxisome proliferator-activated receptor gamma (PPRAγ) pathway in DN....
Normally, Cdk5 kinase, a Ser/Thr kinase of the cyclin dependent kinase family is essential for neuronal development, neuronal migration, cortical layering, synapse formation and behavioral functions [2]. The kinase targets a large number of neuronal protein substrates with proline directed Ser/Thr residues, which accounts, in part, for its importance in the nervous system. Its role stems from i...
This Article contains errors in the Reference list. Reference 33 is incorrectly listed as reference 26 and references 26–32 are incorrectly listed as references 27–33 respectively. The correct references are listed below: 26 Zhang, J. et al. Nuclear localization of Cdk5 is a key determinant in the postmitotic state of neurons. 27 Liang, Z. et al. Cdk5 regulates activity-dependent gene expressio...
Cyclin-dependent kinase 5 (Cdk5)/p35 is a serine/threonine kinase, and its activity is detected primarily in postmitotic neurons. Mice lacking Cdk5/p35 display migration defects of the cortical neurons in the cerebrum and cerebellum. In this study, we demonstrate that although most brainstem nuclei are found in their proper positions, the motor nucleus of the facial nerve is ectopically located...
