Question

What is the usual effect of a nuclear response to a signal transduction pathway? A transcription factor changes the activity of a gene, which leads to a change in the production of mRNA. Protein kinases are phosphorylated so that the signal transduction pathway results in the opening of nuclear pores. Amino acid sequences are changed to ensure that specific protein kinases are created. An ion channel may open or close, depending on the cellular response warranted. the activity of an enzyme changes to be increased or decreased depending on the ligand bound and the cellular response needed.

Explanation / Answer

It is asked what is the nuclear response of a signal transduction pathway.

mostly, all the signal transduction pathways continue their cascade by phosphorylating or dephosphorylating or methylating or demethylating the enzymes ahead of the cascade. most of the transduction pathways end uup in changing the expression levels of a particular mRNA. the pathways may stimulate or inhibit the expression. therefore, the nuclear response would be the change in the activity of a gene by a transcription factor, that would lead to change in expression of mRNA.
