pptr-1 (O18178, W08G11.4) notes

Deep research: the falcon and perplexity-lite run failed (falcon timeout; perplexity unavailable). No deep-research file.
PMID:25535836 is abstract-only in the cache; the PMC full text (PMC4296509) was read through the PubMed MCP for context only.

Key findings

• B56 PP2A subunit that regulates AKT-1 PMID:19249087.
• Predominantly cytosolic PMID:19249087.
• P granule assembly via MEG dephosphorylation PMID:25535836.
• pptr-1 mutant P granules are unstable PMID:21127218.
• Full PP2A (LET-92/PAA-1/PPTR-1) is needed for UV resistance in older adults PMID:33315870.

Curation decisions

• The 4 generic protein binding rows (AKT-1, MEG-1, MEG-3, MEG-4) are removed as uninformative; the interactions are captured elsewhere.
• Lifespan, heat, lipid storage, dauer and signal transduction rows are kept as non-core; nucleus (IBA) is kept as non-core.
• Core functions: GO:0072542 protein phosphatase activator activity in PP2A (GO:0000159), in GO:0046627 and GO:1903863.
