Vitamin D BP (VitD BP), also called VDB, DBP, Group Specific Component (Gc) or macrophage-activating factor (DBP- or Gc-MAF), is a member of the albumin family. These plasma/body fluid proteins have a conserved pattern of cysteine motifs that form binding domains. VitD BP is predominantly produced by hepatic parenchymal cells. It transports VitD, activates macrophages and osteoclasts, and enhances C5a chemotactic activity. Over 80 variant alleles have been identified, some of which correlate with osteoporosis or prostate cancer. Human and mouse VitD BP share 78% aa identity.

Detection of Vitamin D BP by Western Blot
Legumain is required for VDBP processing and regulation. (A) Purified VDBP from human plasma (1.9 μM) was incubated in legumain assay buffer (pH 5.8) at 37 °C with or without purified active bovine legumain (2 μM) for 5 h before gel electrophoresis and immunoblotting of VDBP (n = 1). (B–H) Wild-type (Lgmn+/+) and legumain-deficient (Lgmn−/−) mice were treated with 50 µg/kg 25(OH)D3 (n = 6–7) or an equal volume vehicle (n = 7, control) subcutaneously every two to three days (four times in total). Tissues were harvested 24 h after the final injection (day 8). (B) One representative immunoblot of VDBP and GAPDH (housekeeping) in kidney and liver (n = 4). (C–F) Quantification of VDBP immunoband (IB) intensity as arbitrary units (ARBU) relative to GAPDH in immunoblots represented in (B) (n = 4). (C) Hepatic VDBP 45 kDa immunoband. (D) Renal VDBP 45 kDa immunoband. (E) Hepatic VDBP 55 kDa immunoband. (F) Renal VDBP 55 kDa immunoband. (G) Plasma VDBP concentration (μg/mL) was measured by ELISA (n = 6–7). (H) Hepatic VDBP mRNA expression relative to the geometric mean of CT values of four housekeeping controls (2− delta delta CT, n = 5). (C–H) Data represent mean ± SEM. Two-way ANOVA. # p < 0.05, ## p < 0.01, ### p < 0.001 vs. different genotype, same treatment. Numbers (n) represent individual biological replicates.
