Abstract
Complementary DNA (cDNA) corresponding to mouse nestin intermediate filament protein, a specific marker for neural stem cells, was isolated and characterized. The complete sequence comprised 5983 base pairs encoding 1821 amino acids, and the deduced polypeptide was similar to rat (84%), hamster (73%), and human (62%) nestin. Southern blots showed that mouse nestin was a single-copy gene, and Northern blots detected a 6.0 kilobase mRNA transcript. When the cDNA was overexpressed as an enhanced green fluorescent fusion protein in COS7 cells, nestin immunoreactivity appeared in the filamentous cytoskeletal network. Accordingly, biologically active mouse nestin cDNA may offer an important new tool for stem cell research.
