CRISPR-U™ Gene Knockout Cell Line Strategy

PSME1 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 PSME1 Knockout model in cell line by CRISPR-U™-mediated genome engineering.

Summary The 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes, a 20S core and a 19S regulator. The 20S core is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. The 19S regulator is composed of a base, which contains 6 ATPase subunits and 2 non-ATPase subunits, and a lid, which contains up to 10 non-ATPase subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides. The immunoproteasome contains an alternate regulator, referred to as the 11S regulator or PA28, that replaces the 19S regulator. Three subunits (alpha, beta and gamma) of the 11S regulator have been identified. This gene encodes the alpha subunit of the 11S regulator, one of the two 11S subunits that is induced by gamma-interferon. Three alpha and three beta subunits combine to form a heterohexameric ring. Alternative splicing results in multiple transcript variants.
