Does direct gene activation involve a second-messenger system?
No, direct gene activation typically does not involve a second-messenger system. Direct gene activation involves specific transcription factors binding directly to gene promoter regions to regulate gene expression. Second-messenger systems are typically involved in signal transduction pathways that lead to changes in protein activity or cell function, rather than directly activating genes.
What does a second messenger always do?
read it:)
Cellular responses to hormones that initiate second-messenger systems include?
Possible activation of several different second messenger systems.
Why is a second messenger not necessary in a steroid hormone?
Steroid hormones can directly diffuse across the plasma membrane and bind to intracellular receptors, forming a hormone-receptor complex that directly affects gene expression. This direct mechanism eliminates the need for a second messenger system, unlike peptide hormones that require a second messenger to transmit the signal inside the cell.
What was the second NASA mission to Mercury called?
"Messenger".
What is the difference between bio melatonin and melatonin?
Bio-Melatonin is a branded product containing 3mg of melatonin in an immediate release formulation.
Is melatonin a herb?
Melatonin is a supplement.
In mammals the second messenger nitric oxide is produced from?
Arginine
Which of the following does not act as a second messenger in the second messenger system calmodulin or inositol triphosphate or cyclic AMP?
inositol triphosphateInositol triphosphate (IP3) and diacylglycerol (DAG) are important second messengers. Their formation begins with the binding of an extracellular regulatory
What is the difference between first messenger and second messenger?
The first messenger is nothing but referred to the molecule that brings information upto the cell surface. Once this molecule transfers signal to cell, it is taken over by the well known second messenger to take it further to nucleus through various other signaling molecules down the cascade.
What news does the Second Messenger announce?
The suicide of Jocasta, Oedipus' wife.
Melatonin is secreted by what gland?
Melatonin is secreated by the pineal gland.
