ClustalW alignment of the amino acid sequences of the COOH termini of Afr1, Bni4, Yer158c, Candida albicans Bni4 (AAT73074), human phactr-3/scapinin (NM080672), and proteins of unknown function from Drosophila melanogaster (LD44321) and Caenorhabditis elegans (NP_492478). Identical residues are highlighted in black and similar residues in gray. The PP1 binding motif is amino acids 831 to 833 in Bni4.
