PLPP/CIN-mediated NF2-serine 10 dephosphorylation regulates F-actin stability and Mdm2 degradation in an activity-dependent manner.
Title: PLPP/CIN-mediated NF2-serine 10 dephosphorylation regulates F-actin stability and Mdm2 degradation in an activity-dependent manner.
PLPP/CIN deletion inhibited NEDD4-2 ubiquitination, and diminished the responsiveness of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor by facilitating NEDD4-2-mediated ubiquitination of GluA1 subunit under physiological condition. PLPP/CIN overexpression reversed these effects. These PLPP/CIN-mediated processes were required for the increased seizure severity and its progression in response to kaini...

Results provided novel evidence that PLPP is involved in controlling dendritic spine as well as synaptic plasticity. It showed also for the first time the role of PLPP in GluN functionality via regulation of GluN2A interaction with postsynaptic proteins. These findings suggest that PLPP/CIN may play an important role in information storage and recall capacity, which manifests as a learning memory.

Dimer formation is essential for an intermolecular arginine-arginine-tryptophan stacking interaction that positions a critical histidine residue in the substrate specificity loop of chronophin for PLP coordination.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
