RAMB4 is a ubiquitin-proteasome system (UPS)-stressor. RAMB4 inhibits ubiquitin-mediated protein degradation upstream of the 20S proteasomal catalytic activites. RAMB4 triggers a ubiquitin-proteasome-system (UPS)-stress response without affecting 20S proteasome catalytic activities. Anticancer activity.

Description

RAMB4 is a ubiquitin-proteasome system (UPS)-stressor. RAMB4 inhibits ubiquitin-mediated protein degradation upstream of the 20S proteasomal catalytic activites. RAMB4 triggers a ubiquitin-proteasome-system (UPS)-stress response without affecting 20S proteasome catalytic activities. Anticancer activity[1].

In Vitro

RAMB4 (0-30 µM; 48 hours) treatment produces a dose dependent reduction in the viability of HPV16-positive SiHa and Caski cells and HPV-39-positive ME180 cervical cancer cell lines respectively[1].
RAMB4 reduces the cell viability of exponentially growing HeLa cervical cancer cells in a dose-dependent fashion with an IC50 value of 2 µM[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[1]

Cell Line: Keratinocytes, SiHa, CaSki and ME180 cells
Concentration: 5, 10, 15, 20, 25, 30 µM
Incubation Time: 48 hours
Result: Produced a dose dependent reduction in the viability of HPV16-positive SiHa and Caski cells and HPV-39-positive ME180 cervical cancer cell lines respectively with minimal effects on the viability of primary human keratinocytes and with IC50 similar to the obtained with HeLa cells.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
