General description

Recombinant, human β2-microglobulin fused at the N-terminus to a His•Tag sequence and expressed in E. coli. Subsequently cleaved with CNBr to remove the His•Tag sequence. Extracellular protein that is non-covalently associated with the α-chains of class I MHC molecules. Used as a marker for various tumors and for kidney disease. The purified protein functions similarly to the native protein in in vitro models of amyloid fibril extension.

The endocytic reabsorption of proteins in the proximal tubule requires a complex machinery and defects can lead to tubular proteinuria. The precise mechanisms of endocytosis and processing of receptors and cargo are incompletely understood. EHD1 belongs to a family of
