Uptake and degradation of filamentous actin and vitamin D-binding protein in the rat.
Tissue uptake and degradation of 125I-tyramine-cellobiose-labelled filamentous actin, vitamin D-binding protein (DBP) and actin-DBP complex were studied in the rat. Actin and actin-DBP complex were cleared from plasma at a faster rate than was DBP. About 40% of injected actin was recovered in the liver between 10 and 30 min after administration. Of the total radioactivity recovered in the liver...

متن کاملVitamin D-binding protein prevents vitamin D deficiency and presents vitamin D for its renal activation.
Two mouse models in which the vitamin D-binding protein (DBP) or megalin, a DBP receptor, were knocked out have recently confirmed that DBP is essential for normal vitamin D homeostasis, and have revealed a major pathway for vitamin D activation (1, 2). DBP is also known as the group-specific component of serum (Gc-globulin). It is a highly polymorphic 58 kDa glycoprotein, which has been used a...
متن کاملVitamin D Binding Protein and Bone Health
Vitamin D binding protein (DBP) is the major carrier protein of 25-hydroxyvitamin D (25(OH) D) in the circulation, where it may serve roles in maintaining stable levels during times of decreased 25(OH) availability and in regulating delivery of 25(OH) D to target tissues. Several genetic polymorphisms of DBP have been described that lead to phenotypic changes in the protein that may affect affi...
متن کاملThe variation in free 25-hydroxy vitamin D and vitamin D-binding protein with season and vitamin D status
PURPOSE Serum 25-hydroxy vitamin D [25(OH)D] varies greatly with season at northern latitudes. The purpose of this study was to determine if the seasonal variations in serum total 25(OH)D are followed by a concomitant variation in free 25(OH)D or if the variation is damped by alterations in the binding capacity of DBP. METHODS Serum was collected from 540 healthy blood donors (60% men; mean a...
