Activity summary

Musashi 1 also known as Msi1 is an RNA-binding protein with a mass of about 39 kDa. Msi1 is present in high levels in neural tissue and certain stem cells. It works mechanically by recognizing and binding to specific RNA sequences impacting the fate of the mRNA. Musashi 1 regulates the translation and stability of its target mRNA affecting protein synthesis at the post-transcriptional level. Its expression is not limited to neural tissues but is also detected in other tissues where stem or progenitor cells are present.

Biological function summary

In neural stem cells and other tissue types Musashi 1 plays an important role in maintaining stem cell identity. Musashi 1 forms part of a complex that controls the translation of mRNAs involved in cell fate decisions. It acts by repressing or activating the translation of key regulatory proteins that guide stem cell maintenance and differentiation processes. This protein is also involved in cellular proliferation by influencing the translation of mRNAs tied to cell cycle regulation.

Pathways

The function of Musashi 1 lies within critical signaling pathways such as Notch and Wnt. It facilitates these pathways by regulating the translation of downstream effectors which are necessary for cellular communication and differentiation. Musashi 1 associates with proteins like Numb a known Notch signaling inhibitor and β-catenin from the Wnt pathway modulating their effects on cell cycle progression and stem cell fate.

Associated diseases and disorders

Musashi 1’s abnormal expression is often linked to conditions like glioblastoma and colorectal cancer. High levels of Musashi 1 can promote tumor growth due to its role in cell proliferation and differentiation pathways. In glioblastoma its expression relates closely with other oncogenic proteins such as Numb and Notch altering normal regulatory mechanisms. In colorectal cancer Musashi 1’s interaction with β-catenin further drives tumorigenesis highlighting its potential as a target for therapeutic interventions.

    ab199838 staining Musashi 1 / Msi1 in HepG2 cells. The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab199838 at a 1/100 dilution (shown in red) and Alexa Fluor® 488 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker ab195887, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 488), at a 1/250 dilution (shown in green). Nuclear DNA was labelled with DAPI (shown in blue).

    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

    This product also gave a positive signal under the same testing conditions in HepG2 cells fixed with 100% methanol (5 min).
