Indicators
Cystatin-B (98 aa, ~11 kDa) is encoded by the human CSTB gene. This protein is involved in the regulation of cathepsins.
Indicators
Cystatin-C (146 aa, ~16 kDa) is encoded by the human CST3 gene. This protein is involved in the inhibition of cysteine proteinases.
Indicators
A non-essential sulfur-containing amino acid in humans, related to cystine, Cysteine is important for protein synthesis, detoxification, and diverse metabolic functions. Found in beta-keratin, the main protein in nails, skin, and hair, Cysteine is important in collagen production, as well as skin elasticity and texture. Also required in the manufacture of amino acid taurine, Cysteine is a component of the antioxidant glutathione, and plays a role in the metabolism of essential biochemicals such as coenzyme A, heparin, and biotin. (NCI04)
Indicators
Not considered one of the 20 amino acids, Cystine is a sulfur-containing derivative obtained from oxidation of cysteine amino acid thiol side chains. It functions as an antioxidant and protects tissues against radiation and pollution, slowing the aging process. It also aids protein synthesis. Cystine is abundant in many proteins of skeletal tissues and skin, and found in insulin and digestive enzymes chromotrypsinogen A, papain, and trypsinogen. (NCI04)
Tests
Cytomegalovirus (CMV) tests check for signs of CMV in your blood, sputum, or other body fluids. CMV is a virus in the herpes family. Other types of herpes viruses include the viruses that cause chickenpox and mononucleosis (mono) .
Tests
The determination of cytoplasmic CD223 expression in a biological specimen.
Tests
A fibrin degradation product used mainly to help rule out venous thromboembolism when clinical probability is low.
Indicators
A fibrin breakdown fragment — most useful for ruling out venous thromboembolism when clinical probability is low.
Indicators
This gene plays a role in signal transduction, regulation of transcription and enhancement of apoptosis.
