Biochemical and genetic tests have revealed that a liver protein called NTCP is a functional receptor for hepatitis B and D viruses, which should lead to an improved understanding of the infections caused by these viruses and assist the development of new intervention strategies.
A combination of single-molecule imaging and an in vitro model of the cell cortex has allowed the interactions between actin filaments and filaments made of myosin II to be studied in detail.
Individual granule cells within the cerebellum-the region of the brain that coordinates movement and supports the learning of new motor skills-receive both sensory and motor input streams: an arrangement that may help the brain to use feedback to fine-tune movement.
A protein complex that enables cells to transport substances across their membranes, and that typically consists of four subunits, can also function as two hemicomplexes, each with two subunits.

A protein called PVRL4 has a central role in a number of cancers that originate in epithelial tissue, and anti-PVRL4 antibodies could be used to treat some of these cancers.
The cisternae of the Golgi contain two functionally distinct domains: the central areas, which remain stationary, and the edges or rims, which are mobile.
The eye produces a protein that inhibits the growth of blood vessels in the deep retina, which includes the photoreceptor layer, and disruption of this process can lead to blindness.
Synergistic interactions with PI(4,5)P2 and activated Rho1, which are enriched at the apical membrane of tubular organs, facilitate tight apical targeting of the formin Diaphanous.
