What is a regulatory protein associated with membrane-bound receptor molecules?

G-proteins are regulatory proteins associated with membrane-bound receptor molecules. They facilitate signal transduction by relaying messages from activated receptors to other intracellular signaling components.


What is a G protein?

G protein is one of a number of guanosine triphosphate (GTP)-binding, regulatory proteins that serve as membrane-bound transducers of chemically and physically coded information; they are intermediaries in transmembrane signaling pathways that consist of three proteins: receptor, G protein, and effector. The G protein becomes activated upon binding GTP. The latter is subsequently slow hydrolyzed to GDP. When the hydrolysis is complete, the regulatory effect of the G protein is terminated and it is then available for reactivation by binding GTP.


Can a mutation cause a protein to be overexpressed?

Yes, mutations can potentially lead to overexpression of a protein by altering the regulation of gene expression or by affecting the stability of the protein. Mutations that occur in the regulatory regions of a gene can disrupt the normal control mechanisms, resulting in increased production of the protein.


A typical gene consists of regulatory sites?

A typical gene consists of regulatory sites such as promoters and enhancers, which dictate when and how much the gene is expressed. These regulatory elements interact with transcription factors to control gene expression and play a critical role in determining the level of protein produced by the gene. Mutations in regulatory sites can lead to dysregulation of gene expression, causing disease.


What is the smallest segment of DNA needed to produce a polypeptide or protein?

The smallest segment of DNA needed to produce a polypeptide or protein is a gene. A gene contains the instructions for making a specific protein through the process of transcription and translation. The gene includes sequences that code for the protein as well as regulatory regions that control its expression.

In the control of gene expression in bacteria a regulatory gene a has its own promoter?

The regulatory gene a has its own promoter to enable transcription of the gene. This promoter allows for the synthesis of the regulatory protein encoded by gene a, which can then regulate the expression of target genes in response to specific signals or conditions in the bacterial cell. By controlling the production of this regulatory protein, bacteria can fine-tune their gene expression patterns for adaptation and survival.


What is considered to be a regulatory protein of the myofilaments?

Tropomyosin and troponin are called regulatory proteins because they act like a switch to determine when the fiber can contract and when it cannot.

What activates protein kinase A?

Protein kinase A is activated by the binding of cyclic AMP (cAMP) to its regulatory subunits, causing the catalytic subunits to be released and become active.


What is difference between a structural gene and a nonstructural gene?

The difference between a structural gene and a nonstructural gene can be explained that structural gene is a gene encoding the amino acid sequence of a protein. Non-regulatory gene. A structural gene is a gene that codes for any RNA or protein product other than a regulatory element (i.e. regulatory protein)and then it makes proteins in the cell. However, the nonstructural gene is different from structure gene, for example (nonstructural gene)NS1 Influenza Protein is created by the internal protein encoding, linear negative-sense, single stranded RNA, NS gene segment; which found in Influenzavirus A, Influenzavirus B and Influenzavirus C;


Are troponin and tropomyosin contractile or regulatory proteins?

Troponin is a regulatory protein while tropomyosin is a contractile protein. Troponin is involved in regulating muscle contraction by controlling the interaction between actin and myosin. Tropomyosin works in conjunction with troponin to regulate the binding of myosin to actin during muscle contraction.

Does an internal regulatory protein prevent cell from entering anaphase if chromosomes have not attached to spindle fibers?

Yes, an internal regulatory protein called the spindle assembly checkpoint (SAC) monitors the attachment of chromosomes to spindle fibers. If chromosomes are not correctly attached, the SAC delays progression to anaphase by inhibiting the activity of the anaphase-promoting complex (APC) until all chromosomes are properly aligned. This ensures accurate segregation of chromosomes during cell division.
