MMP20
O60882
Physiology
insertion of a CHR-2 SINE retroposon in exon 2 of MMP20 which would result in premature truncation of the MMP20 protein owing to stop codons in all possible reading frames of the CHR-2 SINE. The length of the MMP20 SINE ranges from 302 bp (B. musculus) to 318 bp (B. physalus). This mutation is found in eight investigated species of baleen whales. Other inactivating mutations (nonsense and frameshift mutations) are found in various species N
