PPM Star Catalogue

The PPM Star Catalogue (Positions and Proper Motions) is an astrometric catalog of about 379,000 stars on the J2000/FK5 system, published from 1988 to 1993.

PPM1A

PPM1A (PP2Cα), protein phosphatase Mg2+/Mn2+ dependent 1A, is a human PP2C-family serine/threonine phosphatase at 14q23.1 that dephosphorylates Smad2/3 to terminate TGF-β signaling and acts as a RelA phosphatase with tumor suppressor-like activity.

PPM1D

PPM1D (Wip1, PP2Cδ) is a chromosome 17q gene encoding a p53-induced serine/threonine phosphatase that terminates the DNA damage response; amplified in cancers and recurrently mutated in chemotherapy-associated clonal hematopoiesis.

PPmoney

PPmoney, originally Wanhui Tourong, was a Chinese P2P lending platform founded in Guangzhou in 2012 by Chen Baoguo, the city's largest before the 2020 shutdown.

PPO inhibitor herbicides

PPO inhibitor herbicides are weed killers that block the enzyme protoporphyrinogen oxidase, which plants need to build chlorophyll; they are classified as HRAC Group 14.

PPoma

PPoma, or pancreatic polypeptidoma, is a rare non-functioning pancreatic endocrine tumor hypersecreting pancreatic polypeptide; it causes only non-specific symptoms, is diagnosed late, often metastasizes to the liver, and can occur with MEN-1.

PPP1CB

PPP1CB (PP1B, PP1Cβ) is a human gene at 2q23 encoding PP1cβ, one of three catalytic subunits of serine/threonine protein phosphatase 1; dominant smooth-muscle myosin phosphatase isoform; variants cause Noonan syndrome-like disorder with loose anagen hair 2.

PPP1R12A

PPP1R12A (MYPT1) is a human gene on chromosome 12 encoding the targeting subunit of myosin phosphatase, which regulates actomyosin contractility; de novo loss-of-function variants cause holoprosencephaly spectrum, urogenital malformations, and disorders of sex development.

PPP1R15A

PPP1R15A (GADD34), gene ID 23645 on 19q13.33, encodes a stress-inducible regulatory subunit of protein phosphatase 1 that dephosphorylates eIF2α Ser51, terminating the integrated stress response; its constitutive paralogue is PPP1R15B (CReP).

PPP2R1A

PPP2R1A (PR65A, PP2A-Aalpha, MRD36) is a chromosome 19 gene encoding the alpha scaffolding subunit of protein phosphatase 2A; mutated in gynecologic cancers and causing Houge-Janssens syndrome 2 when de novo missense variants arise.

PPRO

PPRO is a London-based payments infrastructure company, founded around 2006, whose single API lets payment providers and merchants accept local payment methods across more than 85 markets.

PPS submachine gun

The PPS (Russian for Sudayev's submachine gun), also known as the PPS-42 and PPS-43, is a Soviet submachine gun designed by Alexei Sudayev during the German invasion, adopted in 1942 and 1943.

PPSh-41

The PPSh-41 is a Soviet submachine gun designed by Georgy Shpagin and adopted in 1940; 5.4 million were built, making it World War II's most mass-produced submachine gun.

PPV-CVP-FLUID study

PPV-CVP-FLUID is a randomized trial comparing pulse pressure variation versus central venous pressure guidance for intraoperative fluid management in intracranial tumor surgery; 60 patients, PPV group had better hemodynamic stability and less postoperative fluid.

PR domain zinc finger protein 1

PRDM1 (PR domain zinc finger protein 1, also Blimp-1 or PRDI-BF1) is a human chromosome 6q21 transcriptional repressor with five C2H2 zinc fingers; it drives plasma cell differentiation, tissue-resident lymphocyte programs, and acts context-dependently in cancer.

PR Newswire

PR Newswire is a press release distribution service founded in New York in 1954 by Herbert Muschel, owned by Cision since its 2016 acquisition, serving journalists, newsrooms, and financial terminals.

PR-domain zinc finger protein PRDM5-like

PR-domain zinc finger protein PRDM5-like (IPR017125), centered on PRDM5/BCS2/PFM2: a vertebrate-arisen PRDM-family transcriptional repressor with 16 zinc fingers that regulates collagen and ECM genes, is epigenetically silenced in solid tumors, and causes brittle cornea syndrome 2 when mutated.

Pr0211

Pr0211 (2MASS J08421149+1916373) is a late G/K star in the Beehive Cluster, Cancer, hosting the hot Jupiter Pr0211 b (2012) and eccentric super-Jovian Pr0211 c (2016); first multi-planet system in an open cluster.

Pr1−xSrxNiO2
