Abstract
Radial glial progenitors (RGPs) are highly elongated epithelial cells that give rise to most stem cells, neurons, and glia in the vertebrate cerebral cortex. During development, the RGP nuclei exhibit a striking pattern of cell-cycle-dependent oscillatory movements known as interkinetic nuclear migration (INM), which we previously found to be mediated during G1 by the kinesin Kif1a and during G2 by cytoplasmic dynein, recruited to the nuclear envelope by the nucleoporins RanBP2 and Nup133. We now identify Nup153 as a nucleoporin anchor for Kif1a, responsible for G1-specific basal nuclear migration, providing a complete model for the mechanisms underlying this basic but mysterious behavior, with broad implications for understanding brain development.
期刊介绍:
Cell Reports publishes high-quality research across the life sciences and focuses on new biological insight as its primary criterion for publication. The journal offers three primary article types: Reports, which are shorter single-point articles, research articles, which are longer and provide deeper mechanistic insights, and resources, which highlight significant technical advances or major informational datasets that contribute to biological advances. Reviews covering recent literature in emerging and active fields are also accepted.
The Cell Reports Portfolio includes gold open-access journals that cover life, medical, and physical sciences, and its mission is to make cutting-edge research and methodologies available to a wide readership.
The journal's professional in-house editors work closely with authors, reviewers, and the scientific advisory board, which consists of current and future leaders in their respective fields. The advisory board guides the scope, content, and quality of the journal, but editorial decisions are independently made by the in-house scientific editors of Cell Reports.
