Mouse tissues express multiple splice variants of prominin-1.

Prominin-1, a heavily glycosylated pentaspan membrane protein, is mainly known for its function as a marker for (cancer) stem cells, although it can also be detected on differentiated cells. Mouse prominin-1 expression is heavily regulated by splicing in eight different variants. The function or the expression pattern of prominin-1 and its splice variants (SVs) is thus far unknown.
