PP1 bound on spinophilin, a close homolog of neurabin and another major synaptic PP1 anchoring protein, does not play a role in long term depression [LTD] induction, which suggests that neurabin plays a privileged role in nanodomain targeting of PP1 in LTD induction.
Title: Distinct Roles of Protein Phosphatase 1 Bound on Neurabin and Spinophilin and Its Regulation in AMPA Receptor Trafficking and LTD Induction.
Data indicate that the protein phosphatase 1 (PP1) and nuclear membrane protein lamina associated polypeptide 1B (LAP1B) LAP1B:PP1 complex can be immunoprecipitated from cerebral cortex.
Title: The nuclear envelope protein, LAP1B, is a novel protein phosphatase 1 substrate.
Data show that the PP1:spinophilin holoenzyme is dynamic in solution, which allows for an increased capture radius of spinophilin and is likely important for its biological role.
Title: Flexibility in the PP1:spinophilin holoenzyme.
Data are consistent with the postsynaptic gephyrin scaffold acting as a platform for protein phosphatase 1 (PP1), which regulates gephyrin cluster size by dephosphorylation of gephyrin- or cytoskeleton-associated proteins.
Title: Regulation of postsynaptic gephyrin cluster size by protein phosphatase 1.

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.
