Proteins are especially important because they are involved in a variety of processes, such as cell signaling, immune response, and enzyme activity.
Further Explanation:
Proteins are a type of macro molecule that has a different variety of functions for the cell. These are polymers of amino acids that are linked together by peptide bonds. The proteins serve as the bodybuilding molecules, as well as the enzymes that aid in several biochemical reactions in the body. Immunoglobulin is a protein that protects the body from a different type of pathogen, and also, insulin is a cell-signaling molecule.
Immunoglobulin (Ig) or antibodies are glycoproteins that are synthesized on an encounter with an antigen. They are a part of the immunoglobulin super family of proteins.This super family comprises of the group of proteins present at the cell surface that works in cell-adhesion, as receptor molecules, or may act in signal transduction.
Integrins are cell-surface proteins that bind to the neutrophils to provide them with a sticky surface. In the inflammatory response, these leukocytes are brought from the bloodstream circulation to the infection site. This can be carried out only in the presence of integrins. Excess integrin will bind more neutrophils, and thus, in the bloodstream, the neutrophils count would become low. Integrins are cell-surface proteins that are involved in the leukocytes adhesion because of their sticky surface. They are found during the inflammatory response.
