CRISPR-U™ Gene Knockout Cell Line Strategy

RAB4A 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 RAB4A Knockout model in cell line by CRISPR-U™-mediated genome engineering.
Target gene info
Official symbol RAB4A
Gene id 5867
Organism Homo sapiens
Official full symbol RAB4A, member RAS oncogene family
Gene type protein-coding
Also known as HRES-1, HRES-1/RAB4, HRES1, RAB4
Summary This gene is a member of the largest group in the Ras superfamily of small GTPases, which regulate membrane trafficking. The encoded protein is associated with early endosomes and is involved in their sorting and recycling. The protein also plays a role in regulating the recycling of receptors from endosomes to the plasma membrane. Alternatively spliced transcript variants have been observed for this gene.
Genomic regions Chromosome 1
