Mdm2 binding protein (MTBP) is a nuclear factor implicated in control of DNA replication initiation and S-phase progression through interactions with replication proteins such as Treslin/TICRR and CDC45, supporting origin firing and genome stability. MTBP also interfaces with cell-cycle checkpoint and stress-response signaling, linking replication dynamics to proliferation control. Dysregulated MTBP expression has been associated with altered replication stress tolerance and chromosomal instability observed across multiple tumor contexts, making it a useful locus for studying pathways that couple DNA replication with oncogenic growth programs. Functional interrogation of MTBP informs mechanisms governing replication timing, DNA damage signaling, and mitotic fidelity in human cells.
MTBP Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MTBP locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MTBP. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt MTBP function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of MTBP-disrupted clones.
