Tissue-specific variation in 5'-terminal exons of mouse Anoctamin 1 transcript induces N-terminal variation of its protein via alternative translational start sites.

Abstract excerpt

Anoctamin 1 (encoded by the Ano1 gene) is a Ca2+-activated Cl- channel critical to many physiological functions. It has been speculated that Ano1 expression is regulated in a tissue-dependent manner via alternative promoters. However, variation in the 5'-end sequence of mouse Ano1 (mAno1) and its tissue-dependent regulation are poorly understood. We identified a novel 5'-terminal exon (designated exon 1a) of...
