Mystery Solved? Biologists find a unique version of a filament-forming protein in human cells that insects lack

Jul 7, 2016

Providing structural support and protection against such conditions as blistering, cataracts and dementia, intermediate filament proteins (IFs) reside in every cell in the human body. In insects, however, IFs are nowhere to be found.

Scientists have posited that in these creatures another kind of protein is responsible for key IF functions; but exactly what kind — or even where to start looking — has been a mystery.
