When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ...

A natural vitamin A transporter, RBP4, can awaken latent HIV through NF-κB signalling, offering a new angle for cure ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have determined the atomic-level structure of a zinc-transporter protein, a molecular machine that regulates levels ...

Transport proteins are responsible for the ongoing movement of substrates into and out of a biological cell. However, it is difficult to determine which substrates a specific protein can transport.

Researchers have identified a previously unknown mechanism by which the kidney precisely controls calcium excretion. The ...

Scientists have determined structures of a transporter protein involved in the movement of neurochemicals such as serotonin and dopamine, unearthing multiple mechanisms that can guide drug development ...

Researchers from ETH Zurich have succeeded in introducing large quantities of unnatural amino acids into bacteria, enabling ...

A team of scientists has answered a long-standing question in cell biology, uncovering how the cell’s main energy currency, ATP, is transported into the endoplasmic reticulum (ER). Disrupted energy ...
