Model for mechanism of intragenic complementation
between act1 alleles (after Ayscough and Drubin, 1996).
Actin monomers encoded by ACT1, act1-x, and
act1-y are represented by white, black, and gray
circles, respectively. The ability of hypothetical actin-binding
proteins A and B to interact with actin filaments comprising wild-type
actin, each mutant actin singly, or a combination of mutant actins is
schematized. The PH growth phenotype of strains containing such actin
filaments is also indicated.
