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. mRNA splicing helps to remove these sequences, leaving a more favourable sequence. mRNA splicing is an essential event in the post-transcriptional modification process of gene expression. SWAP helps to control this process in all cells except gametes.
