Genet. 89:401-406(1992). 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 GC1F, GC1S, AND GC2. THE CC SEQUENCE SHOWN IS THAT OF THE GC2 ALLELE. CC -!- SIMILARITY: BELONGS TO THE ALB/AFP/VDB FAMILY. CC -!- DOMAIN: CONTAINS 3 ALBUMIN DOMAINS.
