what are gtp binding proteins?
155099
GTP-Binding Proteins. Regulatory proteins that act as molecular switches. They control a wide range of biological processes including: receptor signaling, intracellular signal transduction pathways, and protein synthesis.

AKAP. A-kinase-anchoring protein. Any of a growing family of proteins (20 and counting) that bind regulatory subunits of cAMP-dependent protein kinase (protein kinase A) and localise its activity to various molecular targets within the cell. Segen's Medical Dictionary.

G protein-coupled receptor (GPCR), also called seven-transmembrane receptor or heptahelical receptor, protein located in the cell membrane that binds extracellular substances and transmits signals from these substances to an intracellular molecule called a G protein (guanine nucleotide-binding protein).

cGMP acts as a second messenger much like cyclic AMP. Its most likely mechanism of action is activation of intracellular protein kinases in response to the binding of membrane-impermeable peptide hormones to the external cell surface.

Explanation: During the elongation stage of translation, GTP is used as an energy source for the binding of a new amino bound tRNA to the A-site of the ribosome. It is also used as an energy source for the translocation of the ribosome towards the 3' end of the mRNA.

The R package gtable is designed to help construct and manipulate layouts containing graphical elements. The standard grid package in R provides low-level functions to define viewports, and place graphical elements (grobs) at specific locations within the device window.

CREB-TF (CREB, cAMP response element-binding protein) is a cellular transcription factor. It binds to certain DNA sequences called cAMP response elements (CRE), thereby increasing or decreasing the transcription of the genes.

Green Florescent Protein (GFP) Purification. GFP is soluble but contains several stretches of hydrophobic amino acids. In the presence of high salt buffer the three dimensional structure of the protein changes such that the hydrophobic regions of the protein are exposed and the hydrophilic regions are shielded.

Aside from the sugar (glycan or carbohydrate) antigens, the red blood cell membrane contains three types of protein that carry blood group antigens: single-pass proteins, multi-pass proteins, and glycosylphosphatidylinositol (GPI)-linked proteins.

Cyclic guanosine monophosphate (cGMP) is a unique second messenger molecule formed in different cell types and tissues. cGMP targets a variety of downstream effector molecules and, thus, elicits a very broad variety of cellular effects.

3.2 Trimeric G proteins. G proteins are attached to the cytosolic face of the plasma membrane, where they serve as relay proteins between the receptors and their target signalling proteins. Trimeric G proteins interact with 7TM receptors and are all heterotrimeric, having structurally different α, β and γ subunits.

A gated channel protein is a transport protein that opens a "gate," allowing a molecule to pass through the membrane. Gated channels have a binding site that is specific for a given molecule or ion. A stimulus causes the "gate" to open or shut.

A monomeric G-protein (also known as small G protein or small GTPases, is the umbrella term for a family of signal transducing proteins. These comprise of: Rab, Arf, Ras, Ran and Rho, which are also vital in the growth of cells, as well as cell transport, motility, cytokinesis and cell differentiation.

Gq alpha subunit. From Wikipedia, the free encyclopedia. guanine nucleotide binding protein (G protein), q polypeptide. Identifiers.

Ligand-gated ion channels (LGICs) are integral membrane proteins that contain a pore which allows the regulated flow of selected ions across the plasma membrane.

GFP Antibody detects GFP, YFP, and CFP-tagged proteins exogenously expressed in cells. This antibody does not detect RFP-tagged proteins. ... GFP has become a very useful tool as a fusion protein that reports gene expression, traces cell lineages and defines subcellular protein localizations (1).

Gq protein alpha subunit is a family of heterotrimeric G protein alpha subunits. ... G alpha subunits may be referred to as Gq alpha, Gαq, or Gqα. Gq proteins couple to G protein-coupled receptors to activate beta-type phospholipase C (PLC-β) enzymes.
