Preclinical studies suggest that Cdk5
is a gene that is important for the normal wiring of the brain during early development and may be involved in some neurodegenerative disorders, including ALS, Parkinsons and Alzheimers disease.
A[beta] activates NLRP3 inflammasomes via the P2X7R receptor or TLR4-MyD88-NF-[kappa]B pathway, [alpha]-synuclein activates the toll-like receptor 2 (TLR2) which promotes the assembly of NLRP3 and induces IL-1[beta] synthesis, ROS activates NLRP3 through c-Abl kinase or upregulates CTSB activity, Cdk5
could activate NLRP3 inflammasome, caspase-1 could cleave [alpha]-synuclein into a highly aggregation-prone specie, and NLRP10 attenuates A[beta]- induced caspase 1 activation and IL-1[beta] release.
Various important kinases regulate tau phosphorylation, including cyclin-dependent kinases (CDK2 and CDK5
), GSK-3[beta], mitogen-activated protein kinase (MAPK), extracellular signal-regulated protein kinase 1/2 (ERK1/2), c-Jun N-terminal kinase (JNK), Akt, protein kinase a (PKA), and calcium-calmodulin protein kinase 2 (CaMKII).

Conversion of p35 to p25 deregulates Cdk5
activity and promotes neurodegeneration.
James Bibb, Associate Professor of Neurology and Neurotherapeutics at UT Southwestern said that if people inhibit Cdk5
, then the vast majority of brain tissue stays alive without oxygen for up to one hour, which tells them that Cdk5
is a central player in nerve cell death.
GSK3, PKC, PKA, 14-3-3 Mode 1, PKG, p38MAPK, cdk5
, CKII, cdc2, ATM, and CKI are the most predicted kinases involved in phosphorylation of many serine and threonine residues in IRS-2.

Creating highly selective CDK2 compounds is a challenge due to the identity of ATP binding subsites within CDK1, CDK2, and CDK3 molecules; CDK2 also possesses 92% and 80% sequence identity in CDK5
and CDK6 molecules, respectively (RCSB Protein Data Bank code: 1b38).
Interestingly, cyclin-dependent kinase 5 (Cdk5
) was reported to mediate phosphorylation at Ser56 of vimentin .
Las CDK son una familia de quinasas serina/treonina implicadas en la regulacion de la division celular (cdksl, 2, 3, 4, 6 y 7), la transcripcion (cdks7, 8 y 9) y el mantenimiento de la estructura del citoesqueleto (cdk5
ISLAMABAD -- Lower levels of an enzyme called p35, which is vital for activating a protein called Cdk5
for brain development, may be linked with schizophrenia.
