Structural organization of nuclear lamins A, C, B1, and B2 revealed by superresolution microscopy.

abstract：:Microtubule (MT) organization is essential for many cellular events, including mitosis, migration, and cell polarity. Fidgetin (Fign), an ATP-dependent, MT-severing protein, contributes to the regulation of MT configuration by cutting and trimming MT polymers. Functions of Fign have been indicated in neurite outgrowth...

As opposed to cytosolic ribosomes, however, these ribosomes are not thought to contain 5S rRNA. For this reason, it has been unclear whether 5S rRNA, which can be detected in mitochondrial preparations...
