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.

Aging-induced proteostatic changes in the rat hippocampus identify ARP3, NEB2 and BRAG2 as a molecular circuitry for cognitive impairment.
Title: Aging-induced proteostatic changes in the rat hippocampus identify ARP3, NEB2 and BRAG2 as a molecular circuitry for cognitive impairment.
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.

The current results suggest a possible role for spinophilin in neuronal plasticity induced by environmental enrichment.
Title: Enriched environment increases spinophilin mRNA expression and spinophilin immunoreactive dendritic spines in hippocampus and cortex.
expression of spinophilin (SPL) could enhance the regulatory function of RGS8 on the M3-mAChR system, but the acceleration function of RGS8 on the M2-mediated signaling could not be enhanced by SPL

selective targeting of PP1gamma1 to F-actin by neurabins in intact cells requires both the canonical PP1-binding motif and an auxiliary PP1gamma1-selectivity determinant
Title: Selective targeting of the gamma1 isoform of protein phosphatase 1 to F-actin in intact cells requires multiple domains in spinophilin and neurabin.
Associatively conditioned rats had more spinophilin in their dendritic spines than controls; changes in the number of dendritic spines must occur during learning and account in part for memory.
Title: Associative Pavlovian conditioning leads to an increase in spinophilin-immunoreactive dendritic spines in the lateral amygdala.
Regions of spinophilin that lack the revised Actin-binding Domain (ABD) do not co-localize with phalloidin-labeled actin, suggesting that the ABD contributes to directing the subcellular distribution of spinophilin.

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.
