Can the first sentence of this article be rewritten so that the definition does not contain the defined term? 69.140.152.55 (talk) 02:13, 18 May 2008 (UTC)

Can a definition of isoform be given? Can this be defined interms of the physical characteristics of species that constitute an isoform group? As opposed to a definition of what it takes to make an isoform (i.e. for proteins, coming from SNP modifications of DNA, etc). For small molecules, one would discuss the various isomers (same connectivity, although not necessarily the same geometry, e.g. chirality). One might discuss molecules with the same molecular weight, but not the same atoms, or with the same atoms but with different connectivities. Can protein, or glycan isoforms be defined in terms of primary, secondary, tertiary and quantenary structure? —Preceding unsigned comment added by 148.168.40.4 (talk) 18:47, 14 August 2008 (UTC)

First sentence now says "A protein isoform is any of several different forms of the same protein." but what counts as the same protein ? It can't be amino acid sequence. Does it require a minimum degree of homology and substantially similar biochemical behaviour ? Is there an implication that the different isoforms exist in the same cell or organism ?

Hi
Hi everyone, I plan to expand this stub by adding some sections: definition and mechanism. And I will rewrite the 1st paragraph in the beginning of the page and change the title of the section glycoforms. I will also add some references that I was used in the editing. I think some figures from alternative splicing article is very useful in this page. So I may add some figures in mechanism section. I will upload my work some time next week.

Definition unclear
The introductory sentence says that the term "isoform" is ambiguous, as it describes two different concepts: "one-gene-multiple-proteins" and "multiple-genes-similar-proteins". But then in the rest of the article it's not clear which of the two concepts is being described. Most of the article seems to talk about the "one-gene-multiple-proteins" concept via alternative splicing, but the AMPK example in the definition section seems to refer to the "multiple-genes-similar-proteins" concept. This is very confusing. AxelBoldt (talk) 14:36, 4 April 2017 (UTC)


 * I rewrote the lead to clear up the definition. See if it helps. --Mark viking (talk) 21:18, 4 April 2017 (UTC)


 * this is a lot better, thanks! AxelBoldt (talk) 20:10, 5 April 2017 (UTC)
