SAR1A
SAR1A or Sar1 is a protein involved in membrane trafficking. It is a GTPase found in COPII vesicles. It regulates the assembly and disassembly of COPII coats.GDP-bound Sar1 interacts with […]
COPI
COPI is a protein complex that coats vesicles transporting proteins from the cis end of the Golgi complex back to the rough endoplasmic reticulum (ER) where they were originally synthesized […]
COPII
COPII is a type of vesicle coat protein that transports proteins from the rough endoplasmic reticulum to the Golgi apparatus. This process is termed anterograde transport in contrast to the […]
Cytochrome C1
Cytochrome C1 is formed in the cytosol and targeted to the mitochondrial intermembrane space.
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 […]
