title: Hepatic and renal expression of senescence marker protein-30 and its biological significance.
abstract: A novel rat hepatic protein was detected and isolated, the amount of which is downregulated in an androgen-independent manner with ageing. This protein was designated as senescence marker protein-30 (SMP30). Senescence marker protein-30 turned out to be identical to a hepatic calcium-binding protein called regucalcin (RC). This review gives an overview of SMP30 in its structure, expression and possible physiological function(s). A hypothetical role of SMP30 in ageing and calcium homeostasis is also discussed.
