CRISPR-U™ Gene Knockout Cell Line Strategy

LILRB4 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 LILRB4 Knockout model in cell line by CRISPR-U™-mediated genome engineering.
Target gene info
Official symbol LILRB4
Gene id 11006
Organism Homo sapiens
Official full symbol leukocyte immunoglobulin like receptor B4
Gene type protein-coding
Also known as CD85K, ILT-3, ILT3, LIR-5, LIR5
Summary This gene is a member of the leukocyte immunoglobulin-like receptor (LIR) family, which is found in a gene cluster at chromosomal region 19q13.4. The encoded protein belongs to the subfamily B class of LIR receptors which contain two or four extracellular immunoglobulin domains, a transmembrane domain, and two to four cytoplasmic immunoreceptor tyrosine-based inhibitory motifs (ITIMs). The receptor is expressed on immune cells where it binds to MHC class I molecules on antigen-presenting cells and transduces a negative signal that inhibits stimulation of an immune response. The receptor can also function in antigen capture and presentation. It is thought to control inflammatory responses and cytotoxicity to help focus the immune response and limit autoreactivity. Multiple transcript variants encoding different isoforms have been found for this gene.
Genomic regions Chromosome 19
