Application

Nocodazole has been shown to enhance CRISPR genome editing efficiency. To see other small molecule CRISPR enhancers, visit sigma.com/CRISPR-enhancers.

Biochem/physiol Actions

Nocodazole is an antimitotic agent that disrupts microtubules by binding to β−tubulin and preventing formation of one of the two interchain disulfide linkages, thus inhibiting microtubule dynamics, disruption of mitotic spindle function, and fragmentation of the Golgi complex. Nocodazole arrests the cell cycle at G2/M phase and also prevents phosphorylation of the T cell antigen receptor and inhibits its activity. Nocodazole stimulates the intrinsic GTPase activity of tubulin and activates the JNK/SAPK signaling pathway and induces apoptosis in several normal and tumor cell lines. Nocodazole has been shown to enhance CRISPR homology-directed repair (HDR) efficiency and increase Cas9-mediated editing frequencies.

The perinuclear stacks of the Golgi apparatus maintained by dynamic microtubules are essential for cell migration. Activation of Akt (protein kinase B, PKB) negatively regulates glycogen synthase kinase 3β (GSK3β)-mediated tau phosphorylation, which enhances tau binding to microtubules and microtubule...

The cohesin complex, which is essential for sister chromatid cohesion and chromosome segregation, also inhibits resolution of sister chromatid intertwinings (SCIs) by the topoisomerase Top2. The cohesin-related Smc5/6 complex (Smc5/6) instead accumulates on chromosomes after Top2 inactivation, known to lead...

Abscission is the final step of cell division, mediating the physical separation of the two daughter cells. A key player in this process is the microtubule-severing enzyme spastin that localizes at the midbody where its activity is crucial to cut...

Replication stress, a hallmark of cancerous and pre-cancerous lesions, is linked to structural chromosomal aberrations. Recent studies demonstrated that it could also lead to numerical chromosomal instability (CIN). The mechanism, however, remains elusive. Here, we show that inducing replication stress...
