Just to clarify, a multiple sequence alignment is a representation of a set of homologous sequences, i.e. a set of sequences that have a common evolutionary origin. In a MSA every row corresponds to a sequence and every column corresponds to a position in the protein that is equivalent between the different proteins.
It is one of the most commonly used types of files in Bioinformatics
