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 GRB2 Knockout
model in cell line by CRISPR-U™-mediated genome engineering.

Official full symbol
growth factor receptor bound protein 2
Also known as
ASH, EGFRBP-GRB2, Grb3-3, MST084, MSTP084, NCKAP2
Genomic regions
Chromosome 17
Summary
The protein encoded by this gene binds the epidermal growth factor receptor and contains one SH2 domain and two SH3 domains. Its two SH3 domains direct complex formation with proline-rich regions of other proteins, and its SH2 domain binds tyrosine phosphorylated sequences. This gene is similar to the Sem5 gene of C.elegans, which is involved in the signal transduction pathway. Two alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Project Comprehensive Difficulty Assessment
According to the Red Cotton database: the GRB2 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.
