Recombinant Human REG1A Protein

Product Name: Recombinant Human REG1A Protein
Catalog #:  hRP-1386
Manufacture:  LD Biopharma, Inc.

Human lithostathine-1-alpha (REG1A) gene is a type I subclass member of the Reg gene family. The Reg gene family is a multigene family grouped into four subclasses, types I, II, III and IV, based on the primary structures of the encoded proteins. This gene encodes a protein that is secreted by the exocrine pancreas. It is associated with islet cell regeneration and diabetogenesis and may be involved in pancreatic lithogenesis. Reg family members REG1B, REGL, PAP and this gene are tandemly clustered on chromosome 2p12 and may have arisen from the same ancestral gene by gene duplication. mRNA profiling data indicated that REG1A maintains much high level expression in human fetal brain than adult brain, which regulates neurite outgrowth.

Full-length mature human REG1A (145 aa) gene was constructed with 27 aa N-terminal T7/His/TEV Tag and expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
