Can someone explain/give example of post transcription changing with pre and post hormones. Thanks

??? Are you asking about hormones affecting post-transcriptional modifications? Hrm...I really can't think of an example!

You mean post-transcriptional modification of hormones? The only example I can think of at the top of my head is Insulin. But I'm also thinking of post-translational modification. There are so many post-transcriptional/translational modifications that occur, though, that's specific to proteins, though.

Click and let me know what you mean exactly from the explanation given.

Also, did you mean that or how hormones regulate the production of products post-transcriptionally?

Yea i think insulin and pre insulin is an example. Thanks for the help!

Remember that pre-insulin -> insulin is post-translational modification, not post-transcriptional.

Yeah, that's what I remembered. Or that's the "main" insulin modification every text book talks about.

would the changing of the digestive enzymes from zymogens to active proteins be considered as post-translational modification?

Strictly speaking, thats defined as protein processing. Post-translational modification typically refers to modification of a peptide chain within the ER/golgi.
