CRISPR-U™ Gene Knockout Cell Line Strategy

PCSK9 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 PCSK9 Knockout model in cell line by CRISPR-U™-mediated genome engineering.
Target gene info
Official symbol PCSK9
Gene id 255738
Organism Homo sapiens
Official full symbol proprotein convertase subtilisin/kexin type 9
Gene type protein-coding
Also known as FH3, FHCL3, HCHOLA3, LDLCQ1, NARC-1, NARC1, PC9
Summary This gene encodes a member of the subtilisin-like proprotein convertase family, which includes proteases that process protein and peptide precursors trafficking through regulated or constitutive branches of the secretory pathway. The encoded protein undergoes an autocatalytic processing event with its prosegment in the ER and is constitutively secreted as an inactive protease into the extracellular matrix and trans-Golgi network. It is expressed in liver, intestine and kidney tissues and escorts specific receptors for lysosomal degradation. It plays a role in cholesterol and fatty acid metabolism. Mutations in this gene have been associated with autosomal dominant familial hypercholesterolemia. Alternative splicing results in multiple transcript variants.
Genomic regions Chromosome 1
