What does isoform mean?
An isoform is a variant of a protein that arises from a single gene but differs in its structure and function due to alternative splicing, post-translational modifications, or other mechanisms. Isoforms play crucial roles in various biological processes, and their diversity allows for complex regulation of cellular functions. The study of isoforms is essential in understanding protein function and its implications in disease. Isoforms can have distinct functions, locations, and interactions, making their study vital in fields like biochemistry and molecular biology.
nounA variant of a protein that is encoded by a single gene but differs from other variants of the protein due to alternative splicing or other post-translational modifications.
- A variant of a protein encoded by a single gene.
- A specific type of protein isoform.
"The different isoforms of the protein were found to have distinct functions in the cell."
"The study identified multiple isoforms of the gene."
"Isoforms of the protein were detected in the patient's blood."
The plural form 'isoforms' is used to refer to multiple variants of a protein.
"The study identified multiple isoforms of the gene."

Etymology of isoform
The term 'isoform' originated from the Greek words 'isos,' meaning equal, and 'morph,' meaning form. It is used to describe different forms of a protein that have the same origin but differ in structure.
How isoform is actually used
The term 'isoform' is commonly used in molecular biology and biochemistry to describe protein variants.
