General description
SILu™ Prot Clusterin is a recombinant, stable isotope-labeled human Clusterin which incorporates [13C6, 15N4]-Arginine and [13C6, 15N2]-Lysine. Expressed in human 293 cells, it is designed to be used as an internal standard for bioanalysis of Clusterin in mass-spectrometry. SIL™ Prot Clusterin is a heterodimer of 2 subunits (alpha and beta) consisting of 427 amino acids (including N-terminal polyhistidine and V5 tags), with a calculated molecular weight of 50 kDa.
Biochem/physiol Actions
Clusterin is a secreted glycosylated, 80-kDa disulfide-linked heterodimer of alpha and beta subunits (produced by internal cleavage). Clusterin is expressed in virtually all tissues and found in all human fluids. It is involved in numerous physiological processes important for carcinogenesis and tumor growth, including anti-apoptotic cell survival, cell cycle regulation, cell adhesion, tissue remodeling and lipid transportation. Clusterin also exists as a nuclear protein. The secreted form of Clusterin has extracellular chaperone and anti-apoptotic activities while the nuclear form acts as a proapoptotic factor.
