S100A1, a member of the large EF-hand family of Ca(2+)-binding proteins, is mainly expressed in the mammalian heart. To assess the underlying mechanisms for cell- and tissue-specific expression we isolated and characterized the mouse S100A1 gene. The gene displays a high degree of homology to the human and rat genes, especially in the exonic sequences. In its promoter region and the first intron, we identified regulatory elements characteristic for cardiac and slow skeletal muscle restricted genes. Transfection assays with luciferase constructs containing different parts of the S100A1 gene demonstrated the active expression in primary mouse cardiomyocytes and that its 5'-upstream region containing a putative cardiac enhancer showed a greatly increased activity. Furthermore, we investigated the expression of the S100A1 mRNA during embryonic mouse development, using in situ hybridization. S100A1 transcripts were first detected in the primitive heart at embryonic day (E) 8, with equal levels in the atrium and ventricle. During development up to E17.5 we detected a shift in the S100A1 expression pattern with lower levels in atrial and high levels in ventricular myocardium. The regulatory elements identified in the mouse S100A1 promoter correspond well with the observed expression pattern and suggest that S100A1 has an important function during heart muscle development.
