Recombinant Human VPS28 Protein

Product Name: Recombinant Human VPS28 Protein
Catalog #:  hRP-0744
Manufacture:  LD Biopharma, Inc.

Human vacuolar protein sorting-associated protein 28 homolog (VPS28) gene encodes a protein involved in endosomal sorting of cell surface receptors via a multivesicular body/late endosome pathway. The encoded protein is one of the three subunits of the ESCRT-I complex (endosomal complexes required for transport) involved in the sorting of ubiquitinated proteins. The two other subunits of ESCRT-I are vesicular protein sorting 23, also known as tumor susceptibility gene 101 (TSG101), and vesicular protein sorting 37. Two alternative transcripts encoding different isoforms have been described.

Full-length human VPS28 (221aa, Isoform_1) gene was constructed with 19aa N-terminal T7 tag and expressed in E.coli as inclusion bodies, refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
