WebNov 3, 2024 · From correlating the diffusion times with IFT train frequencies, we estimated that kinesins tend to attach to the next train passing in the opposite direction. IFT-dynein, however, diffuses longer and lets one or two trains pass before attaching. This might be a direct consequence of the lower diffusion coefficient of the larger IFT-dynein. WebApr 27, 2024 · In addition, for four of the inner dynein isoforms—dyneins a, g, d , and I1 dynein —the distribution of the smaller population of intermediate conformations (IM1 and IM2) was highly correlated with the bend direction, that is, they were found either on DMTs 1 to 4 in principal bend regions or on DMTs 6 to 9 in reverse bends of active ... in case 是什么意思 https://malbarry.com
