Ensemble repeat structure of MaSp1 and MaSp3 genes.

’ER size’ indicates the most common ER in terms of number of poly-A units. ’ER regularity’ provides the proportion of total ER units that have the most common size (e.g., a value of 1 means all ER units are the same size). ’Ave %_ID’ indicates the average percent amino acid identity for homologous poly-A units across all ER units.’% Repeat’ indicates the percentage of the total protein occupied by stereotypical ER units.
