carrier protein

a multiunit transmembrane protein that possesses specific binding sites of a particular molecule and transports that substance across the cell membrane. It does so by reversibly altering its conformation after binding occurs and after resuming its original molecular conformation after transporting and releasing the substance on the other side of the membrane.
See also: uniport, symport, antiport.

binding protein

A generic term for a protein that reversibly binds to various small molecules, including amino acids, sugars, inorganic ions, vitamins and other molecules.

carrier protein

1. A protein that elicits an immune response when coupled with a hapten.
2. A membrane protein for facilitated diffusion of a specific substance into a cell.
See also: protein

carrier protein

membrane proteins that have a high affinity for particular solutes, e.g. glucose, and which facilitate the passage of these solutes through membrane barriers. See also carrier-mediated transport.

The GM2 antigen, coupled to the carrier-protein keyhole limpet hemocyanin (KLH) forms the basis for the vaccine which is then combined with QS-21, an adjuvant which stimulates the immune system, to recognize and destroy cancer cells expressing GM2.
Within this study, 3 sets of the discriminating carrier-protein bound fragments differentiated samples from patients with ovarian cancer and from apparently healthy controls with sensitivities and specificities of up to 93% and 97%, respectively.
Thus, the rate of formation of the biomarker-carrier-protein complex (BC) is proportional to the product of the biomarker concentration [B] and the carrier-protein concentration [C], with a constant of proportionality [k.
The current study brings together a suite of methods and technologies, including novel sample preparation based on carrier-protein capture and enrichment of biomarkers (17), high-resolution mass spectrometric detection, and bioinformatics analysis that adds statistical and procedural robustness to biomarker discovery from blood, and a unique cohort of well-characterized persons with and without Alzheimer disease (AD).
