Prominin-1 (CD133) is a cholesterol-binding protein crucial for stem cell identification. This review highlights its role in cell signaling, membrane dynamics, and tissue homeostasis, impacting cancer development.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- Prominin-1 (CD133) is a membrane glycoprotein recognized as a stem cell marker.
- It is associated with cholesterol and prominent membrane structures.
- CD133 is used for isolating stem cells and cancer stem cells.
Purpose of the Study:
- To review early studies on CD133.
- To describe recent evidence on CD133's involvement in membrane dynamics and signaling.
- To provide a resource for understanding CD133's function in health and disease.
Main Methods:
- Literature review of early and recent studies on Prominin-1 (CD133).
Main Results:
- CD133 is involved in plasma membrane protrusions (microvilli, cilia) and extracellular vesicle release.
- CD133 engages in multiple signaling pathways, including PI3K/Akt, Src-FAK, Wnt/β-catenin, TGF-β/Smad, and MAPK/ERK.
- These functions suggest CD133 regulates cell proliferation, differentiation, migration, and intercellular communication.
Conclusions:
- CD133 is a master regulator of cell signaling and membrane dynamics.
- Its functions are critical for tissue homeostasis and cancer development.
- Further research into CD133's molecular functions is warranted.
