A proposed model of transcriptional regulation of mitochondrial function and ETC complex I by the SIRT1 isoforms. The partial exclusion of N-terminal region in SIRT1 gene modulates its regulatory capability in reversible acetylation of lysine at specific position(s), transcriptional regulation of gene expression, regulation of mitochondrial function, and ETC complex I activity.
