New research identifies a destination for zinc chaperone protein's deliveries

Most people don't think much about zinc. But all living things need zinc for survival. This trace element helps many proteins fold into the right shapes to do their jobs.

Chaperone protein imbalance initiates toxic accumulation of tau in the aging brain

Chaperone protein imbalance can play a significant role in initiating toxic accumulation of tau in the aging brain - an early step in the development of Alzheimer's disease and related neurodegenerative disorders known as tauopathies, a new preclinical study by University of South Florida Health (USF Health) neuroscientists suggests.

DNAJC9 protein plays a key role in protecting histones in the cell nucleus

Histones play an important role in the cell nucleus by packaging DNA into chromatin.

Simple 'designer' pore reproduces selective cellular transport mechanisms

The nucleus is the headquarters of a cell and molecules constantly move across the nuclear membrane through pores. The transport of these molecules is both selective and fast; some 1,000 molecules per second can move in or out.

Study reveals the structure of heat shock proteins that could treat Huntington's disease

In Huntington's disease, a faulty protein aggregates in brain cells and eventually kills them. Such protein aggregates could, in principle, be prevented with a heat shock protein.
