General description
Human prealbumin is a product of chromosome 18. It is a serum protein, synthesized primarily in the liver. It is a tetrameric protein with a molecular weight of 55 kDa. Human prealbumin is composed of four identical non-covalently bound monomers of 127 amino acid residues arranged with tetrahedral symmetry.
Application
Prealbumin from human plasma has been used as a positive control in immunoprecipitation as a reference standard in quantitative rocket immunoelectrophoresis for quantification of cerebrospinal fluid.
Human prealbumin was used to study reduced transthyretin expression in sera of lung cancer.
Biochem/physiol Actions
Prealbumin levels are indictors of malnutrition and may be modulated during inflammation. It is regarded as potential marker of protein energy malnutrition (PEM) during chronic kidney failure supported dialysis. Low levels of prealbumin poses high risk to heart failure (HF).
Human prealbumin has been observed in carcinoid tumors.
