The functions of biomolecules, including lipids, nucleic acids and especially proteins are determined to a great extent by their structure. This structure–function relationship is a foundation of many ...

Two recently published studies led by Brazilian scientists reveal the key roles of multifunctional proteins, STIP1 and Maspin ...

Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the ...

When two cells "talk" to each other, they often do so through tiny channels called electrical synapses. Unlike chemical ...

A key protein expressed in epithelial “skin” cells plays a critical role in protecting the structure and function of cells in the nervous system of a model nematode, a type of worm, according to new ...

Nucleotides are the fundamental units that make up the genetic material of all living organisms. They are the building blocks of DNA and RNA, which store and transmit genetic information. Nucleotides ...
