Hemagglutinin (influenza)
Influenza hemagglutinin (HA) or haemagglutinin (British English) is a glycoprotein found on the surface of the influenza viruses. It is responsible for binding the virus to cells with sialic acid […]
Signal peptide
A signal peptide (sometimes referred to as signal sequence leader sequence or leader peptide) is a short (5-30 amino acids long) peptide present at the N-terminus of the majority of […]
Intermediate filament
Intermediate filaments (IFs) are cytoskeletal components found in metazoan cells. They are composed of a family of related proteins sharing common structural and sequence features.
Clathrin
Clathrin is a protein that plays a major role in the formation of coated vesicles. Clathrin was first isolated and named by Barbara Pearse in 1975. It forms a triskelion […]
Sigma factor
A sigma factor (σ factor) is a protein needed only for initiation of RNA synthesis. It is a bacterial transcription initiation factor that enables specific binding of RNA polymerase to […]
Ribonuclease
Ribonuclease (commonly abbreviated RNase) is a type of nuclease that catalyzes the degradation of RNA into smaller components. Ribonucleases can be divided into endoribonucleases and exoribonucleases and comprise several sub-classes […]
Somatostatin
Somatostatin (also known as growth hormone-inhibiting hormone (GHIH) or somatotropin release-inhibiting factor (SRIF)) or somatotropin release-inhibiting hormone[citation needed] is a peptide hormone that regulates the endocrine system and affects neurotransmission […]
Serotonin transporter
The serotonin transporter (aka SERT or 5-HTT) is a type of monoamine transporter protein that transports serotonin from the synaptic cleft to the presynaptic neuron.This transport of serotonin by the […]
Lantibiotics
Lantibiotics are a class of peptide antibiotics that contain the characteristic polycyclic thioether amino acids lanthionine or methyllanthionine as well as the unsaturated amino acids dehydroalanine and 2-aminoisobutyric acid.Lanthionine is […]
