CRISPR-U™ Gene Knockout Cell Line Strategy

PPIB 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 PPIB Knockout model in cell line by CRISPR-U™-mediated genome engineering.
Target gene info
Official symbol PPIB
Gene id 5479
Organism Homo sapiens
Official full symbol peptidylprolyl isomerase B
Gene type protein-coding
Also known as B, CYP-S1, CYPB, HEL-S-39, OI9, SCYLP
Summary The protein encoded by this gene is a cyclosporine-binding protein and is mainly located within the endoplasmic reticulum. It is associated with the secretory pathway and released in biological fluids. This protein can bind to cells derived from T- and B-lymphocytes, and may regulate cyclosporine A-mediated immunosuppression. Variants have been identified in this protein that give rise to recessive forms of osteogenesis imperfecta.
Genomic regions Chromosome 15
