Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0006432
UniProt IDQ9UNP9
Primary gene name(s)PPIE
Synonym gene name(s)CYP33
Protein namePeptidyl-prolyl cis-trans isomerase E
Protein functionPPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Combines RNA-binding and PPIase activities. May be involved in muscle- and brain-specific processes. May be involved in pre-mRNA splicing.
Subcellular locationNucleus.
