This module has two highly connected subnetworks representing components of two distinct cellular machines: the mitochondrial ribosome and the endosomal sorting complexes required for transport (ESCRT) complex.
One set of evolutionary features that has received less attention than the evolution of genes or species is the evolution of cellular machines, the self-contained structures in cells with dedicated functions.
This is particularly crucial during cell division, where the microtubules build the cellular machine, called the mitotic spindle, that ensures that each daughter cell receives the correct number of chromosomes (Sawin et al., 1992).
More generally, it is naïve to attribute the emergence of a highly complex, multifunctional cellular machine like the nucleus to a single selective factor.
It put the study of ribosome – the cellular machine that turns the blueprint of life into life itself – on front pages round the world".
All three used a technique known as x-ray crystallography to pinpoint the position of thousands of atoms in the cellular machine known as the ribosome, and all will share one-third of the $1.4 million prize.
Many of the protein protein interactions within a cellular machine are kinetically skewed towards the bound state, so that the machine remains assembled.
As a valid alternative we examined the use of mesenchymal stromal cells (MSCs) as autonomous cellular machines for the constant production of a recently described, fully humanized anti-CD33-anti-CD3 bsAb, which is capable of redirecting human T cells against CD33-expressing leukemic cells.
Protease activation is a necessary cog in the cellular machine under physiological conditions.
More generally, our results present a methodology for the study of subunit architecture of functional multiprotein complexes by revealing mechanistic insights into the role of intrinsically unstructured regions and post-translationally modified subunits within the context of a cellular machine.
The 26S proteasome is a complex cellular machine that contains a 20S central core, a hollow tube composed of multiple proteasome subunits, which contain proteolytic sites.
