概括

在Drosophila神经元中减少的循环素依赖激酶5 (Cdk5) 活性会改变轴突初始段 (AIS) 的线粒体分布. 这种重新分配与Cdk5活性有关,而不是AIS收缩,不太可能是神经退行症的早期原因.

科学领域:

神经科学是一个神经科学.
细胞生物学细胞生物学
遗传学遗传学是一种遗传学.

背景情况:

线粒体分布的变化与与年龄有关的神经退行性疾病有关.
在虫中减少的循环素依赖性激酶5 (Cdk5) 活性会诱导神经退行并影响线粒体的特性.

结论:

改变的Cdk5活性导致线粒体重新分配到轴突初始段 (AIS).
这种线粒体再分配不太可能是Cdk5相关的神经退行症的早期驱动因素.

Translocation of Proteins into the Mitochondria

Translocation of Proteins into the Mitochondria

Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
