What is tyrosine kinase receptor dimerization. Receptor polymorphism and dimerization in drug design?
I suppose I would need a better understanding of what you mean by the latter part of the question. Receptors can be influenced by polymorphisms (different "formula" variations that are expressed in populations which influence binding...Ex replacing a neutral amino acid with a positive affects binding correct?....As far as dimerization as it relates to drug design I must first confess that I'm not a pharmacologist... however my guess would be that they would want to make their products multivalent so that they bind multiple TK's so that they are able to dimerize...(this is merely a guess)
What else can I help you with?
What membrane receptor undergoes dimerization and autophosphorylation?
Receptor tyrosine kinases (RTKs) are membrane receptors that undergo dimerization and autophosphorylation upon ligand binding. This activation leads to the recruitment and activation of downstream signaling molecules in the cell.
The activation of receptor tyrosine kinases is characterized by?
The activation of receptor tyrosine kinases involves ligand binding to the extracellular domain, leading to receptor dimerization and autophosphorylation of tyrosine residues on the intracellular domain. This activation initiates downstream signaling cascades involved in cell growth, differentiation, and survival.
The activation of receptor tyrosine kinases is characterized by what?
Receptor tyrosine kinases, when activated by ligand binding, undergo dimerization and autophosphorylation of tyrosine residues. This promotes the recruitment and activation of downstream signaling molecules, ultimately leading to a cellular response such as cell growth, differentiation, or survival.
Growth factor hormones such as insulin bind to which type of receptor?
tyrosine kinase receptor!!
How do receptor tyrosine kinases function within cellular signaling pathways?
Receptor tyrosine kinases are proteins on the cell surface that receive signals from outside the cell and activate a series of chemical reactions inside the cell. When a signaling molecule binds to the receptor, it triggers the receptor to add phosphate groups to specific tyrosine residues on itself and other proteins, leading to the activation of various signaling pathways that regulate cell growth, division, and survival.

What is the difference of g-protein receptor system and tyrosine kinase receptor?
Receptor tyrosine kinases do not require the use of second messengers while G protein-coupled receptors need.

The receptor for a group of signaling molecules known as growth factors are often?
receptor tyrosine kinases

How are receptor tyrosine kinases activated and what role do they play in cellular signaling pathways?
Receptor tyrosine kinases are activated when a signaling molecule binds to them, causing them to dimerize and phosphorylate each other. This activation triggers a cascade of signaling events that regulate cell growth, division, and differentiation. Receptor tyrosine kinases play a crucial role in cellular signaling pathways by transmitting signals from the cell's environment to the nucleus, influencing gene expression and ultimately controlling various cellular processes.
Compare two ways that the binding of a signal molecule to a receptor protein causes a change in activity the receiving cell?
1. Insulin binding to insulin receptor tyrosine kinase on hepatocyte: increased glucose uptake, increased glycogen and fatty acid production and decreased catabolism in general (decreased gluconeogenesis, lipolysis, and proteolysis). Insulin binding causes receptor dimerization and self-phosphorylation. Phosphorylated receptor recruits scaffold proteins and downstream target proteins and phosphorylate them. Phosphorylated target proteins serve as kinases and activate or deactivate other proteins by phosphorylation, effecting appropriate effects. 2. Erythropoietin binding to EPO cytokine receptor on Common Myeloid Progenitor cell: eventual differentiation into erythrocyte. Cytokine receptor induces the Jak/STAT pathway resulting in altered gene expression by transcription factors, drastically changing the function and morphology of the cell.

What is One of the major categories of receptors in the plasma membrane that reacts by forming dimmers adding phosphate groups then activating relay proteins?
One major category of receptors that acts in this way is receptor tyrosine kinases. When a ligand binds to these receptors, they form dimers and phosphorylate each other on tyrosine residues. The phosphorylated tyrosines then serve as binding sites for relay proteins, initiating intracellular signaling cascades.
