In Vitro Three-Dimensional Culture System Enhances Prostate Cancer Cell Growth

A team of cancer researchers developed a three-dimensional in vitro culture system for growing prostate cancer cells in an environment that closely mimics the in vivo tumor microenvironment. More...

HIV Relies on Host Proteins to Clear the Way to the Nucleus

The ability of HIV to transit the cytoplasm and enter the nucleus of an infected cell was found to depend on the combined activities of two host proteins, the Kinesin-1 motor protein, KIF5B, and the nuclear pore component Nup358. More...

Genome Screen Identifies Host Proteins Required for Flavivirus Infection

A team of molecular virologists employed advanced genome editing techniques to identify the host proteins required by flaviviruses such as dengue and Zika for infection and replication. More...

Crystal Structure Determined for Binding Site of Zika/Dengue Neutralizing Antibodies

An international team of molecular virologists has identified neutralizing antibodies that bind to and block both dengue virus and Zika virus, which may pave the way for development of a vaccine to protect against both viruses simultaneously. More...

Image: The figure depicts the X-ray crystal structure of the serine protease urokinase-type plasminogen activator (green) in complex with a Camelid antibody fragment (orange). The Camelid antibody fragment (nanobody) displays an unusual inhibitory mechanism by binding to the active site region (highlighted in blue) of the serine protease where it mimics the binding of substrate (Photo courtesy of Dr. Tobias-Kromann-Hansen, Aarhus University).

Nanobodies Facilitate Studies of Enzyme Substrate Interactions

The unusual crystal structure of a nanobody in complex with a serine protease enzyme was established by X-ray crystallography. More...
