What is Isoform?
A '''protein isoform''' is any of several different forms of the same [[protein]]. Different forms of a protein may be produced from related [[gene]]s, or may be made from the same gene by [[alternative splicing]]. A large number of isoforms are caused by [[single-nucleotide polymorphism]]s or SNPs, small genetic differences between [[alleles]] of the same gene. These occur at specific individual [[nucleotide]] (building block of dna-strand) positions within a gene. {{science-stub}} [[Category:Molecular biology]] [[Category:Proteins]]
