What (who) is B7 (protein) - definition

FAMILY OF CELL-SURFACE PROTEINS FOUND ON ANTIGEN-PRESENTING CELLS

B7 family; B7 antigens

B7 (protein)

B7 is a type of integral membrane protein found on activated antigen-presenting cells (APC) that, when paired with either a CD28 or CD152 (CTLA-4) surface protein on a T cell, can produce a costimulatory signal or a coinhibitory signal to enhance or decrease the activity of a MHC-TCR signal between the APC and the T cell, respectively.

Protein–protein interaction

PHYSICAL INTERACTIONS AND CONSTRUCTIONS BETWEEN MULTIPLE PROTEINS

List of protein interactions; Protein-protein interactions; Protein protein interaction; Protein interaction; Protein-protein interaction assays; Protein-protein interaction; Protein–protein interactions; Protein-protein interface; Protein protein interfaces

Protein–protein interactions (PPIs) are physical contacts of high specificity established between two or more protein molecules as a result of biochemical events steered by interactions that include electrostatic forces, hydrogen bonding and the hydrophobic effect. Many are physical contacts with molecular associations between chains that occur in a cell or in a living organism in a specific biomolecular context.

Hydrolyzed protein

SOLUTION DERIVED FROM THE HYDROLYSIS OF A PROTEIN INTO ITS COMPONENT AMINO ACIDS AND PEPTIDES

Hydrolyzed Protein; Hydrolized protein; Hydrolysed protein; Protein hydrolysis; Protein hydrolysate

Hydrolyzed protein is a solution derived from the hydrolysis of a protein into its component amino acids and peptides. While many means of achieving this exist, most common is prolonged heating with hydrochloric acid, sometimes with an enzyme such as pancreatic protease to simulate the naturally occurring hydrolytic process.

Wikipedia

B7 (protein)

B7 is a type of integral membrane protein found on activated antigen-presenting cells (APC) that, when paired with either a CD28 or CD152 (CTLA-4) surface protein on a T cell, can produce a costimulatory signal or a coinhibitory signal to enhance or decrease the activity of a MHC-TCR signal between the APC and the T cell, respectively. Binding of the B7 of APC to CTLA-4 of T-cells causes inhibition of the activity of T-cells.

There are two major types of B7 proteins: B7-1 or CD80, and B7-2 or CD86. It is not known if they differ significantly from each other. So far CD80 is found on dendritic cells, macrophages, and activated B cells, CD86 (B7-2) on B cells. The proteins CD28 and CTLA-4 (CD152) each interact with both B7-1 and B7-2.
