Disruption of the single tropomyosin gene in yeast results in the disappearance of actin cables from the cytoskeleton.


The yeast tropomyosin gene, designated TPM1, is present in a single copy per haploid genome and encodes a protein with a predicted molecular weight of 23.5 kd. The protein sequence is homologous to higher cell tropomyosins, including the characteristic hydrophobic-hydrophilic pseudoheptapeptide repeats. Indirect immunofluorescence microscopy reveals that… (More)
