Alignment of the isoforms of MASP1. The deduced amino acid sequences of MASP-1 (MASP1 isoform 1), MASP-3 (MASP1 isoform 2), and MAP-1 (MASP1 isoform 3) were aligned using the BioEdit Software. The dots represent identical amino acids. MASP-1 and MASP-3 contain different C-terminal serine protease domains, whereas MAP-1 does not contain a serine protease domain. Instead the protein contains 17 unique amino acids at the C-terminal end.
