What happens to a protein molecule after it has been translated?

Answer 1

it can undergo activation into a functional protein through clevage of certain amino acid sequencies. a amino acid sequence primary structure can fold to form the secondary and tertiary sturcture and forming bonds. splicing (Thats what the protein undergoes) to form functional protein.Also their is processing such as glycosylation in the ER to help with protein folding into functional enxymes.

Answer 2

That depends entirely on what protein it is.

The first thing that happens (and which actually starts happening *during* translation) is that the polypeptide chain will start to fold. Different bits of cellular machinery - like chaperone proteins - actually help control and guide this.

Often, polypeptide chains require further modification after synthesis. for example, they might have carbohydrate chains added to them ("glycosylation"), lipids added to them, or other non-protein substances. This usually happens in the golgi body - so the translated polypeptide is transported there for this "post-synthetic modification".

Many proteins do not function as monomers, but will bind to, and operate in concert with, other proteins. So the several proteins of the final, functional unit are assembled into the final "holoprotein". This can happen in many different locations.

Finally, the protein needs to be transported to its end-destination. So maybe it is transported to the plasma membrane, or secreted in exocytotic vesicles, or tranported to the nucleus, or wherever else it is supposed to be sent to.

Answer 3

After translation it will be transported to the organelles where it destined for. It also can be secreted to function out of the cell such as in blood stream. There are two main role of proteins which is, they build cell or your body and they can function as biocatalyst which are enzymes.
