U protein

U protein

(Science: molecular biology) Hypothetical protein thought to regulate the transition of cells from G0 to g1 phase of the cell cycle and thus inevitably into s phase. The idea would be that the concentration of this unstable (u) protein would have to exceed a threshold level for triggering progression through the cycle and that this would only happen if the cell had adequate access to growth factors or to nutrients.

Synonym: trigger protein.

protein fractionation

... an uropathogenic strain of E.coli. When I artificially express from a plasmid one of the transcriptional regulator, it results in secretion of a protein factor in the media, which has interesting biological roles. My aim is to purify this unknown factor present in the growth media and to identify ...
