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. [ACTS_RABIT] Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells.

Publication Abstract from PubMed

A high-affinity complex formed between G-actin and plasma vitamin D-binding protein (DBP) is believed to form part of a scavenging system in the plasma for removing actin released from damaged cells. In the study presented here, we describe the crystal structure of the complex between actin and human vitamin D-binding protein at 2.5 A resolution. The complex contains one molecule of each protein bound together by extensive ionic, polar, and hydrophobic interactions. It includes an ATP and a calcium ion bound to actin, but no evidence of vitamin D metabolites bound to the DBP. Both actin and DBP are multidomain molecules, two major domains in actin and three in DBP. All of these domains contribute to the interaction between the molecules. DBP enfolds the end of the actin molecule, principally in actin subdomain 3 but with additional interactions in actin subdomain 1. This orientation is similar to the binding of profilin to actin, as predicted from previous studies. The more extensive interactions of DBP give an affinity for actin some 3 orders of magnitude higher than that for profilin. The larger "footprint" of DBP on actin also leads to an overlap with the actin-binding site of gelsolin domain I.
