GTP-binding protein

[¦jē‚tē¦pē ′bīn·diŋ ‚prō‚tēn]
(cell and molecular biology)
One of a large family of heterotrimeric or monomeric proteins that bind GTP (guanosine 5′-triphosphate) as intermediaries in intracellular signaling pathways. Also known as G protein.

Although there was some thought that NF-kB activation could lead to a decrease in extracellular matrix degradation capacity, in turn leading to impaired angiogenesis [34], NF-kB transcription factors have been found to be effectors of the Rho family, including molecules such as the GTP-binding protein RAC1, during inflammation [19, 36].
Rho-associated kinase (Rho kinase/ROCK), identified as a Rho GTP-binding protein, is a downstream effector of the small GTP-binding protein Rho [1-5].
Vesicle endocytosis requires GTP hydrolysis by the GTP-binding protein dynamin, which participate in fission of the nerve terminal plasma membrane to reform vesicles.
Ephedra monosperma had mostly degradome proteins (profilins, desiccation-related protein, the GTP-binding protein RAN-1, and ceramidase) and had only two secretome proteins that we could detect in this initial comparative study--serine carboxypeptidase and glucan endo-1,3-[beta]-glucosidase.
Among these, the RasD2 gene, encoding a small GTP-binding protein RHES, is predominantly expressed in the striatal region of the brain and is involved in striatal function [34].
CgtA is a highly conserved essential GTP-binding protein, coded by the cgtA gene, belonging to Obg subfamily in prokaryotes (8).
