Struct. Biol. 9:131-136(2002). CC -!- FUNCTION: Multifunctional protein found in plasma, ascitic fluid, CC cerebrospinal fluid, and urine and on the surface of many cell CC types. In plasma, it carries the vitamin D sterols and prevents CC polymerization of actin by binding its monomers. DBP associates CC with membrane-bound immunoglobulin on the surface of B-lymphocytes CC and with IgG Fc receptor on the membranes of T-lymphocytes. CC -!- SUBCELLULAR LOCATION: Secreted. CC -!- POLYMORPHISM: Over 80 variants of human DBP have been identified. CC The three most common alleles are called GC*1F, GC*1S, and GC*2. CC The sequence shown is that of the GC*2 allele. CC -!- SIMILARITY: Belongs to the ALB/AFP/VDB family. CC -!- SIMILARITY: Contains 3 albumin domains.
