Eukaryotic translation initiation factor 4E binding

eIF4E binding: how eIF4E-binding proteins (4E-BP1, 4E-BP2, 4E-BP3) repress cap-dependent translation by competing with eIF4G for eIF4E, and how mTORC1 phosphorylation releases them.

Eukaryotic translation initiation factor 4E binding protein

4E-BPs (eIF4E-binding proteins, 4E-BP1/2/3; yeast Caf20p, Eap1p) are small translational repressors that compete with eIF4G for eIF4E, are inactivated by mTORC1 phosphorylation, and enable eIF3d-dependent translation under stress.

Eukaryotic-signature proteins in Asgard archaea

Eukaryotic-signature proteins (ESPs) are archaeal homologs of protein families once thought unique to eukaryotes, found in Asgard archaea and cited as evidence for their role in eukaryogenesis.

Eulipotyphla

Eulipotyphla, the true insectivores, is a Laurasiatherian mammal order of hedgehogs, shrews, moles, and solenodons in four extant families plus extinct Nesophontidae, defined by nuclear-gene monophyly, parallel venom, and repeated aquatic and fossorial transitions.

Eulophidae biology and host associations

Eulophidae is a large family of chalcidoid parasitoid wasps, with roughly 4,300 to nearly 6,000 described species, whose larvae develop on or inside other insects, mites, and nematodes.

Eulophidae systematics

Eulophidae systematics covers the classification of Eulophidae, the largest family of chalcidoid parasitoid wasps, with about 5,300 described species in five subfamilies including Eulophinae and Tetrastichinae.

Eumeces

Eumeces Wiegmann, 1834, holarctic skinks, is a genus of skinks (Scincidae). Once cosmopolitan, it was shown paraphyletic in 2000 and split, with East Asian/New World species moved to Plestiodon; the name remains valid for a narrower Old World lineage.

Eumenes (potter wasps) is a nearly worldwide genus of solitary Vespidae wasps, about 106 species, known for jug-shaped mud pot nests attached to twigs and petiolate abdomens; revised for the New World in 2018.

Eumetazoa

Eumetazoa ("true animals") is the animal group with true differentiated tissues, a nervous system, and muscle cells, traditionally excluding sponges and Placozoa; its origin is dated to about 634–604 Ma in the early Ediacaran.

Eumycetoma

Eumycetoma, also called Madura foot or maduromycosis, is the fungal form of mycetoma, a chronic subcutaneous infection forming grains, mainly caused by Madurella mycetomatis, endemic in the mycetoma belt, treated with itraconazole, terbinafine, and surgery.

Eunice aphroditois

Eunice aphroditois, the Bobbit worm, is a giant predatory polychaete (up to 3 m) of Indo-Pacific waters that ambushes fish from burrows at night using sensory antennae and powerful jaws; its taxonomy remains controversial.
