Identification and functional characterization of inhibitor-3, a regulatory subunit of protein phosphatase 1 in plants.

Identification and characterization of AtI-2, an Arabidopsis homologue of an ancient protein phosphatase 1 (PP1) regulatory subunit.

PMID:25010794

Arabidopsis DELLA protein degradation is controlled by a type-one protein phosphatase, TOPP4.

Direct TOPP4 interaction/dephosphorylation of RGA and GAI supports GA signaling and substrate-dependent turnover.

PMID:25560878

TYPE-ONE PROTEIN PHOSPHATASE4 regulates pavement cell interdigitation by modulating PIN-FORMED1 polarity and trafficking in Arabidopsis.

Native-promoter and fusion localization show nuclear, plasma-membrane and cytoplasmic pools; direct PIN1 dephosphorylation links TOPP4 to pavement-cell morphogenesis.

PMID:26704640

TOPP4 Regulates the Stability of PHYTOCHROME INTERACTING FACTOR5 during Photomorphogenesis in Arabidopsis.

Direct PIF5 dephosphorylation stabilizes PIF5 in red-light signaling; this differs from the DELLA response. Publisher/PMC full-text passages were additionally inspected online although normal cached retrieval remains abstract-only.

Role of Protein Phosphatase1 Regulatory Subunit3 in Mediating the Abscisic Acid Response.

PMID:35961047

Type one protein phosphatase regulates fixed-carbon starvation-induced autophagy in Arabidopsis.

Full target TOPP4-GST ATG13a dephosphorylation assay complements higher-order TOPP mutant autophagy phenotypes.

Expression of multiple type 1 phosphoprotein phosphatases in Arabidopsis thaliana.

PMID:38851185

A CPF-like phosphatase module links transcription termination to chromatin silencing.

TOPP4 associates with APRF1/LD, but the paper explicitly leaves the direct CPF-module phosphatase substrate unresolved.
