Ecd family

Ecd family (InterPro IPR010770, Pfam PF07093 SGT1): conserved eukaryotic proteins named for Drosophila ecdysoneless. Human member ECD/SGT1 (644 aa) regulates p53, Rb cell cycle control, pre-mRNA splicing, and ER stress.

ECD Ovonics

ECD Ovonics was the trade name of Energy Conversion Devices, an American materials science company founded in Detroit in 1960 by Stanford Ovshinsky, inventor of the Ovonic nickel-metal hydride battery.

Ecdysis

Ecdysis, also called moulting, is the shedding of the cuticle in Ecdysozoa such as arthropods and nematodes. Controlled by ecdysteroids from the Y-organ, MIH, ETH, EH, CCAP, and bursicon, it enables growth but leaves the animal vulnerable.

Ecdysone

Ecdysone, also known as α-ecdysone, is a steroid prohormone that regulates molting and metamorphosis in insects. It was first isolated in crystalline form from silkworm pupae in 1954.

Ecdysozoa

Ecdysozoa is a clade of protostome animals defined by molting, or ecdysis, that includes arthropods, nematodes, tardigrades, and related phyla, with over a million described species.

Ecdysteroid receptor

Ecdysteroid receptor (EcR): invertebrate nuclear receptor binding 20-hydroxyecdysone, functioning as an EcR-USP heterodimer, cloned 1991 in Drosophila, target of dibenzoylhydrazine insecticides and gene-switch systems.

Ecdysterone

Ecdysterone, also known as 20-hydroxyecdysone or β-ecdysone, is a polyhydroxylated steroidal hormone that regulates molting and reproduction in arthropods and also occurs in plants; it is sold as a dietary supplement and monitored by anti-doping authorities.

ECE1

ECE1 (endothelin converting enzyme 1, ECE-1, EC 3.4.24.71) is a human M13 zinc metalloendopeptidase gene on 1p36.12 that converts big endothelin-1 to vasoactive ET-1, with four isoforms, broad peptide substrate specificity, and mutations linked to Hirschsprung disease.

Ecgberht, King of Wessex

Ecgberht (Egbert), King of Wessex 802–839, son of Ealhmund of Kent, exiled in Francia by Offa and Beorhtric; defeated Mercia at Ellendun in 825, briefly conquered Mercia in 829, eighth Bretwalda, father of Æthelwulf.

Echelle grating

An echelle grating is a diffraction grating with coarsely spaced, steeply blazed grooves, operated in high orders to reach very high spectral resolving power, mainly in astronomical spectroscopy.

Echelle spectrometer

An echelle spectrometer, often called an echelle spectrograph, is an optical instrument that records high-resolution spectra using an echelle grating plus a cross disperser; it was devised by George R. Harrison at MIT in 1949.

ECHELON

ECHELON, also known as Project ECHELON, was a global signals intelligence system under the UKUSA agreement that intercepted satellite communications and filtered them by keyword searches.
