CRISPR-U™ Gene Knockout Cell Line Strategy

PTGR1 Gene Knockout Strategy

CRISPR-U™ technology (CRISPR based), developed by Ubigene, is more efficient than general CRISPR/Cas9 technology in double-strand breaking and homologous recombination. With CRISPR-U™, Ubigene has successfully edited over 3000 genes on more than 100 types of cell lines.
To create a Human PTGR1 Knockout model in cell line by CRISPR-U™-mediated genome engineering.
Target gene info
Official symbol PTGR1
Gene id 22949
Organism Homo sapiens
Official full symbol prostaglandin reductase 1
Gene type protein-coding
Also known as LTB4DH, PGR1, ZADH3
Summary This gene encodes an enzyme that is involved in the inactivation of the chemotactic factor, leukotriene B4. The encoded protein specifically catalyzes the NADP+ dependent conversion of leukotriene B4 to 12-oxo-leukotriene B4. A pseudogene of this gene is found on chromosome 1. Alternative splicing results in multiple transcript variants.
Genomic regions Chromosome 9
