The localization of the divergent beta 2-tubulin isotype in the microtubular arrays of Physarum polycephalum.


The beta 2-tubulin isotype of Physarum polycephalum is only 83% identical in amino acid sequence with the constitutively expressed beta 1B-tubulin and the myxamoeba-specific beta 1A-tubulin isotypes. A polyclonal antibody specific for beta 2-tubulin was used to monitor the subcellular distribution of the beta 2-tubulin antigen in the mitotic spindle of the… (More)
