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 200 types of cell lines.
Objective
To create a Human PRPF4B Knockout
model in cell line by CRISPR-U™-mediated genome engineering.

Chromosome 6
Summary
Pre-mRNA splicing occurs in two sequential transesterification steps, and the protein encoded by this gene is thought to be involved in pre-mRNA splicing and in signal transduction. This protein belongs to a kinase family that includes serine/arginine-rich protein-specific kinases and cyclin-dependent kinases (CDKs). This protein is regarded as a CDK-like kinase (Clk) with homology to mitogen-activated protein kinases (MAPKs).

Project Comprehensive Difficulty Assessment
According to the Red Cotton database: the PRPF4B gene is evaluated as high lethality riskin cell line, and the CRISPR gene-editing strategy design is Unknown. Knockout project comprehensive difficulty is thus assessed as Unknown. KO experiment is not recommended.
