Additional file 4: of Human MFAP1 is a cryptic ortholog of the Saccharomyces cerevisiae Spp381 splicing factor Alexander Ulrich Markus Wahl 10.6084/m9.figshare.c.3725200_D4.v1 https://springernature.figshare.com/articles/figure/Additional_file_4_of_Human_MFAP1_is_a_cryptic_ortholog_of_the_Saccharomyces_cerevisiae_Spp381_splicing_factor/4785433 Multiple sequence alignment of yeast MFAP1 orthologs. Multiple sequence alignment of 20 MFAP1 orthologs identified in the analyzed Saccharomycotina species. The alignment was built with the MUSCLE algorithm (version 3.8.31; [53]) and displayed with Jalview (version 14; [54]). In general, residue color intensity indicates level of sequence identity at that specific position; coloring starts at a sequence identity of 30%. Blue - conserved hydrophobic residues; red – conserved positively charged residues; purple – conserved negatively charged residues; green – conserved polar residues; cyan – conserved tyrosines or histidines; brown – conserved glycines; yellow – conserved prolines.
