In molecular biology the protein domain SWAP is derived from the term Suppressor-of-White-APricot a splicing regulator from the model organism Drosophila melanogaster. The protein domain is found in regulators that control splicing. It is found in splicing regulatory proteins.When a gene is expressed the DNA must be transcribed into messenger RNA (mRNA). However it sometimes contains intervening or interrupting sequences named introns.
