Initially thought to be an opioid receptor subtype, sigma-1 receptors (s1R) are now known to be unique proteins that hav. chaperone-like properties. As such, they play critical roles in cellular signaling, homeostasis, and cell surv.v.l. These roles offer significant insight for understanding homeostasis of normal physiologic processes, and the pathophysiologic consequences of disruption of normal function. Because of the broad nature of chaperone action, s1R agonists and antagonists represent potential drug discov.ry goals for the pharmacotherapeutic treatment of a v.riety of disorders that result from dysfunctional proteins. The present study summarizes the s1R as a pharmacologic chaperone crucial for protein folding and cellular homeostasis. Through literature rev.ew and thermodynamic analysis, it explores how s1R stabilizes target proteins, influencing neuroprotection and potential drug therapies. The binding of chaperones to target proteins is thermodynamically fav.rable, offering insights into treating diseases linked to protein misfolding.
