Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such ...

Researchers found that TEX38 and ZDHHC19 co-localize on the plasma membrane of spermatids and mediate S-palmitoylation of ARRDC5, a crucial protein for spermatogenesis. Disrupting either TEX38 or ...

Voltage-sensing mechanism of voltage-gated ion channels and voltage-sensing phosphatase (VSP). Voltage-gated ion channels are general voltage-sensing proteins that permeates ions in response to the ...

In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an important turning point. The so-called plasma membrane lets cells control ...

Structure of the newly decoded protein found in the membrane of sperm cells. Colours mark the different units of the protein, which can be put together to make a functioning protein like the building ...
