Crystal structure of human ACBD3 GOLD domain
Structural highlights
Function[GCP60_HUMAN] Involved in the maintenance of Golgi structure by interacting with giantin, affecting protein transport between the endoplasmic reticulum and Golgi. Involved in hormone-induced steroid biosynthesis in testicular Leydig cells (By similarity).[1] Publication Abstract from PubMedPicornaviruses are small positive-sense single-stranded RNA viruses that include many important human pathogens. Within the host cell, they replicate at specific replication sites called replication organelles. To create this membrane platform, they hijack several host factors including the acyl-CoA-binding domain-containing protein-3 (ACBD3). Here, we present a structural characterization of the molecular complexes formed by the non-structural 3A proteins from two species of the Kobuvirus genus of the Picornaviridae family and the 3A-binding domain of the host ACBD3 protein. Specifically, we present a series of crystal structures as well as a molecular dynamics simulation of the 3A:ACBD3 complex at the membrane, which reveals that the viral 3A proteins act as molecular harnesses to enslave the ACBD3 protein leading to its stabilization at target membranes. Our data provide a structural rationale for understanding how these viral-host protein complexes assemble at the atomic level and identify new potential targets for antiviral therapies.
