CRISPR-U™ Gene Knockout Cell Line Strategy

CDK8 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 CDK8 Knockout model in cell line by CRISPR-U™-mediated genome engineering.
Target gene info
Official symbol CDK8
Gene id 1024
Organism Homo sapiens
Official full symbol cyclin dependent kinase 8
Gene type protein-coding
Also known as IDDHBA, K35
Summary This gene encodes a member of the cyclin-dependent protein kinase (CDK) family. CDK family members are known to be important regulators of cell cycle progression. This kinase and its regulatory subunit, cyclin C, are components of the Mediator transcriptional regulatory complex, involved in both transcriptional activation and repression by phosphorylation of the carboxy-terminal domain of the largest subunit of RNA polymerase II. This kinase regulates transcription by targeting the cyclin-dependent kinase 7 subunits of the general transcription initiation factor IIH, thus providing a link between the Mediator complex and the basal transcription machinery. Multiple pseudogenes of this gene have been identified. Alternative splicing results in multiple transcript variants.
Genomic regions Chromosome 13
