CRISPR-U™ Gene Knockout Cell Line Strategy

PNP 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 PNP Knockout model in cell line by CRISPR-U™-mediated genome engineering.
Target gene info
Official symbol PNP
Gene id 4860
Organism Homo sapiens
Official full symbol purine nucleoside phosphorylase
Gene type protein-coding
Also known as NP, PRO1837, PUNP
Summary This gene encodes an enzyme which reversibly catalyzes the phosphorolysis of purine nucleosides. The enzyme is trimeric, containing three identical subunits. Mutations which result in nucleoside phosphorylase deficiency result in defective T-cell (cell-mediated) immunity but can also affect B-cell immunity and antibody responses. Neurologic disorders may also be apparent in patients with immune defects. A known polymorphism at aa position 51 that does not affect enzyme activity has been described. A pseudogene has been identified on chromosome 2.
Genomic regions Chromosome 14
