WebMar 21, 2024 · Two families of motor proteins, dynein and the kinesins, transport cargoes along microtubules, whereas the myosin superfamily are actin motors. Among the different motors, only dynein and myosin VI (also known as MYO6) have been shown to mediate retrograde transport from the cell periphery to the cell interior. WebMay 5, 1997 · Chlamydomonas flagellar inner-arm dynein consists of seven subspecies (a–g), of which all but f contain actin as subunits. The mutant ida5 and a new strain, ida5-t, lack four subspecies (a, c, d, and e).These mutants were found to have mutations in the conventional actin gene, such that its product is totally lost; ida5 has a single-base …
