Although well\u2010characterized biochemically and structurally, its substrate selectivity remains unclear: in vitro, Sirt1 appears promiscuous, while in vivo it activates particular processes in response to different stimuli. Emerging evidence indicates that selectivity arises from multiple regulatory layers beyond the catalytic site. Here we review how post\u2010translational modifications (PTMs) \u2012 including phosphorylation, acetylation, and glycosylation \u2012 modulate activity, localization, and substrate affinity. For instance, phosphorylation at S27\/T530 (by JNK1) or S682 (by HIPK2) affects nuclear translocation, substrate targeting, or complex formation with cofactors such as AROS and DBC1. Protein\u2013protein interactions, for example with DBC1, PACS2, and transcription factors, further direct Sirt1 to specific substrates or compartments, functioning as allosteric regulators. Spatial compartmentalization, including nucleocytoplasmic shuttling and localization to promyelocytic leukemia nuclear bodies (PML\u2010NBs), integrates Sirt1 into defined signaling contexts. Moreover, liquid\u2013liquid phase separation (LLPS) may concentrate Sirt1 and substrates within condensates, enhancing its selectivity. Overall, Sirt1 specificity emerges from PTMs, interactions, localization, and phase behavior \u2012 offering a framework for developing selective modulators in metabolic and age\u2010related diseases.\n
