What else can I help you with?
A protein on the surface of HIV can attach to what proteins on the surface of healthy human cells?
HIV's surface protein, gp120, can attach to CD4 receptors on healthy human cells. This interaction allows HIV to enter and infect the cell by binding to the CCR5 or CXCR4 co-receptors on the cell surface.
What hormone requires a G-protein?
G-protein coupled receptors (GPCRs) are the largest family of cell surface receptors, they mediate a response to a huge variety of signalling molecules (eg. hormones). A few examples of hormones that use GPCRs are; adrenalin, prostaglandins and glucagon.
When was G protein-coupled receptors database created?
G protein-coupled receptors database was created in 1998.
Do epinephrine use g-protein linked receptors?
Yes, epinephrine binds to G-protein coupled receptors, specifically the α and β adrenergic receptors. Activation of these receptors leads to various physiological responses such as increased heart rate, bronchodilation, and vasoconstriction.
What protein forms a bridge between exposed vessel wall collagen and platelet surface receptors?
The protein that forms a bridge between exposed vessel wall collagen and platelet surface receptors is von Willebrand factor (vWF). When blood vessels are damaged, vWF binds to collagen fibers in the vessel wall and simultaneously interacts with platelet glycoprotein receptors, particularly GPIb-IX-V, facilitating platelet adhesion and aggregation at the site of injury. This process is crucial for the formation of a stable platelet plug during hemostasis.
What are the cell surface receptorss?
G-protein, ion-channel and enzyme-linked protein receptors.
A protein on the surface of HIV can attach to what proteins on the surface of healthy human cells?
HIV's surface protein, gp120, can attach to CD4 receptors on healthy human cells. This interaction allows HIV to enter and infect the cell by binding to the CCR5 or CXCR4 co-receptors on the cell surface.
A specific protein that recognizes certain molecules?
There are antibodies and cell-surface receptors and enzymes; is there a more specific A. in view?
What hormone requires a G-protein?
G-protein coupled receptors (GPCRs) are the largest family of cell surface receptors, they mediate a response to a huge variety of signalling molecules (eg. hormones). A few examples of hormones that use GPCRs are; adrenalin, prostaglandins and glucagon.
The molecules that convert extracellular signals into intracellular ones are?
Cell surface receptors, such as G-protein coupled receptors, receptor tyrosine kinases, and ligand-gated ion channels, are responsible for converting extracellular signals into intracellular ones. These receptors can initiate various downstream signaling pathways that ultimately regulate cellular responses.
When was G protein-coupled receptors database created?
G protein-coupled receptors database was created in 1998.
What do hormones bind to on the surface of target cells?
Hormones typically bind to specific protein receptors located on the surface of target cells. These receptors are responsible for initiating a signaling pathway within the cell in response to the hormone binding, leading to specific cellular responses.
Do epinephrine use g-protein linked receptors?
Yes, epinephrine binds to G-protein coupled receptors, specifically the α and β adrenergic receptors. Activation of these receptors leads to various physiological responses such as increased heart rate, bronchodilation, and vasoconstriction.
What type of receptors are olfactory receptors?
Olfactory receptors are G protein-coupled receptors (GPCRs). These receptors are located in the olfactory epithelium of the nasal cavity and are responsible for detecting odor molecules.
What has the author Lee E Limbird written?
Lee E. Limbird has written: 'Cell surface receptors' -- subject(s): Binding Sites, Binding sites (Biochemistry), Cell Membrane, Cell Surface Receptors, Cell receptors, Endogenous Substances Receptors, Ligands, Methods, Radioligand assay, Receptors, Cell Surface, Receptors, Endogenous Substances
What are the Venus Flytrap receptors?
Venus Flytrap receptors are multimodal 7 transmembrane G-protein coupled receptors activated by extracellular calcium ions.
What protein forms a bridge between exposed vessel wall collagen and platelet surface receptors?

When blood vessels are damaged, vWF binds to collagen fibers in the vessel wall and simultaneously interacts with platelet glycoprotein receptors, particularly GPIb-IX-V, facilitating platelet adhesion and aggregation at the site of injury.
