Abstract
The intermediate filament protein vimentin is involved in a variety of cellular functions both during the normal developmental processes and in human malignancies. We here describe the identification of an alternative vimentin transcript initiating upstream for the canonical vimentin gene promoter and spliced using the vimentin promoter sequence as an intron. Expression analysis showed that the alternative vimentin promoter had the same expression profile as the canonical vimentin gene promoter. The presented data suggest that alternative promoter usage and alternative splicing could be regulatory mechanisms participating in vimentin gene regulation.
