Reaction: CDK5:p25 phosphorylates lamin B1
- in pathway: Deregulated CDK5 triggers multiple neurodegenerative pathways in Alzheimer's disease models
Alzheimer's disease (AD), like many other neurodegenerative diseases, is characterized by nuclear envelope fragmentation. Based on a mouse AD model, nuclear fragmentation is initiated by phosphorylation of nuclear lamins by p25-activated CDK5. The CDK5:p25 complex phosphorylates lamin B1 (LMNB1) at serine residues S23 and S393. Nuclear envelope fragmentation increases access of the CDK5:p25 complex to nuclear proteins and precedes neuronal death (Chang et al. 2011).
