Is it possible to find the same gene in different organisms but those organisms not both produce the protein (or the same protein)?
Answer) the answer of the above question will be yes and it is because of the following reason:
These type of protein are known as isoforms which has same gene but due to post transcriptional modification the sequence of Exon is change which is known as Alternative spilcing and this is the main cause of genetic diversity but not necessarily they are different they can also be same in function. For example one isoform can promote cell survival and other can cause cell death .
Some of the example will be easier to discuss :
1) G-actin almost 6 isoforms are present
2) monoamine oxidase has 2 isoforms
Basically different protein are mainly depend on the person mind setup .
