HRP-0773 Recombinant Human PPIE Protein $300

Recombinant Human PPIE Protein

Product Name: Recombinant Human PPIE Protein
Catalog #:  HRP-0773
Manufacture:  LD Biopharma, Inc.

The protein encoded by human peptidyl-prolyl cis-trans isomerase E (PPIE) gene is a member of the peptidyl-prolyl cis-trans isomerase (PPIase) family. PPIases catalyze the cis-trans isomerization of proline imidic peptide bonds in oligopeptides and accelerate the folding of proteins. This protein contains a highly conserved cyclophilin (CYP) domain as well as an RNA-binding domain. It was shown to possess PPIase and protein folding activities, and it also exhibits RNA-binding activity. Recent data indicated that PPIE specifically interactive with MLL to regulate H3K4me3 activity for down-stream gene transcription activation or repression switch.

Full-length human PPIE (301aa, isoform_1) gene was constructed with 15aa 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.
