Why do mitochondria retain their own genome?

It sounds like science fiction to suggest that every cell in the human body is occupied by a tiny genome-equipped organelle, with which we exist in symbiosis. But in actuality, eukaryotic life is dependent on mitochondria, ...

Researchers define role of Tmem231 in maintaining ciliary function

Researchers reveal how a protein linked to Meckel syndrome (MKS) and other human diseases regulates the membrane composition of cilia, finger-like projections on the surface of cells that communicate signals. The study appears ...

How is the membrane protein folded?

A key factor in the biosynthesis and stable expression of multi-pass transmembrane proteins was discovered, and its loss is thought to cause retinal degeneration. The factor works especially for multi-pass membrane proteins, ...

Cell membrane proteins give up their secrets

Rice University scientists have succeeded in analyzing transmembrane protein folding in the same way they study the proteins' free-floating, globular cousins.

'Vicious cycle' shields, spreads cancer cells

A "vicious cycle" produces mucus that protects uterine and pancreatic cancer cells and promotes their proliferation, according to researchers at Rice University. The researchers offer hope for a therapeutic solution.

Tiny channels carry big information

They say it's the little things that count, and that certainly holds true for the channels in transmembrane proteins, which are small enough to allow ions or molecules of a certain size to pass through, while keeping out ...
