T. Fujita et al., HEPATIC AND RENAL EXPRESSION OF SENESCENCE MARKER PROTEIN-30 AND ITS BIOLOGICAL SIGNIFICANCE, Journal of gastroenterology and hepatology, 13, 1998, pp. 124-131
A novel rat hepatic protein was detected and isolated, the amount of w
hich is downregulated in an androgen-independent manner with ageing. T
his protein was designated as senescence marker protein-30 (SMP30). Se
nescence marker protein-30 turned out to be identical to a hepatic cal
cium-binding protein called regucalcin (RC). This review gives an over
view of SMP30 in its structure, expression and possible physiological
function(s). A hypothetical role of SMP30 in ageing and calcium homeos
tasis is also discussed.
