Crystallographic analysis of the human vitamin D binding protein

Structural highlights

1j78 is a 2 chain structure with sequence from Homo sapiens. The November 2012 RCSB PDB Molecule of the Month feature on Vitamin D Receptor by David Goodsell is 10.2210/rcsb_pdb/mom_2012_11. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

[VTDB_HUMAN] Multifunctional protein found in plasma, ascitic fluid, cerebrospinal fluid, and urine and on the surface of many cell types. In plasma, it carries the vitamin D sterols and prevents polymerization of actin by binding its monomers. DBP associates with membrane-bound immunoglobulin on the surface of B-lymphocytes and with IgG Fc receptor on the membranes of T-lymphocytes.

Publication Abstract from PubMed

The human serum vitamin D-binding protein (DBP) has many physiologically important functions, ranging from transporting vitamin D3 metabolites, binding and sequestering globular actin and binding fatty acids to functioning in the immune system. Here we report the 2.3 A crystal structure of DBP in complex with 25-hydroxyvitamin D3, a vitamin D3 metabolite, which reveals the vitamin D-binding site in the N-terminal part of domain I. To more explicitly explore this, we also studied the structure of DBP in complex with a vitamin D3 analog. Comparisons with the structure of human serum albumin, another family member, reveal a similar topology but also significant differences in overall, as well as local, folding. These observed structural differences explain the unique vitamin D3-binding property of DBP.
