Géraldine Seydoux

Géraldine Seydoux is a French-born American developmental biologist at Johns Hopkins and a Howard Hughes Medical Institute investigator, known for showing that transcriptional repression establishes the germline.

Geraniaceae

Geraniaceae, the geranium family (Geraniales, rosids), includes Geranium, Pelargonium, Erodium, Monsonia, Sarcocaulon, California, and Hypseocharis; herbs and shrubs with five-parted flowers and beaked schizocarp fruits, about 830 species, mainly temperate.

Geraniales

Geraniales is a small order of flowering plants in the rosid clade Malvids, sister to Myrtales, with about 742 species including the geranium family Geraniaceae and its ornamental genera.

Geranium

Geranium (cranesbills) is a genus of about 337 herb species in Geraniaceae, native to temperate and tropical-mountain regions worldwide, with beaked explosive fruits; distinct from Pelargonium, the garden "geranium."

Geranium robertianum

Geranium robertianum, herb Robert or red robin, is a pink-flowered annual or biennial geranium native to the temperate Northern Hemisphere, self-seeding explosively up to 6.5 m, rich in phenolics, and a noxious weed in Washington State.

Geranyl-diphosphate synthase

Geranyl-diphosphate synthase (GPPS) is a trans-prenyltransferase in plant plastids that makes geranyl diphosphate, the common precursor of monoterpenes, stopping chain growth at C10 unlike related enzymes.

Geranylgeranyl reductase, plant/cyanobacteria

Geranylgeranyl reductase (ChlP, CHLP, GGR) is the plastid FAD enzyme of plants and cyanobacteria reducing GGPP to phytyl diphosphate for chlorophyll, tocopherol, and phylloquinone synthesis, unlike archaeal GGRs that fully saturate to phytanyl.

Geranylgeranyl transferase type-1 subunit beta

Geranylgeranyl transferase type-1 subunit beta (PGGT1B) is the beta subunit of GGTase-I, a CaaX prenyltransferase that attaches 20-carbon geranylgeranyl lipids to Rho, Rac, and Rap GTPases, a cancer drug target.

Geranylgeranyl-diphosphate synthase

Geranylgeranyl-diphosphate synthase (GGDPS, GGPPS, EC 2.5.1.29; human gene GGPS1) is an isoprenoid pathway enzyme making GGPP for protein geranylgeranylation; dysregulated in diabetes, liver, lung, kidney and malignant disease, and targeted by bisphosphonate inhibitors.
