Ciliate Biology: Dynamin Goes Nuclear
نویسنده
چکیده
Dynamin and dynamin-related proteins (DRPs) mediate an array of membrane fission processes. A Tetrahymena DRP has adopted a new role, assisting in nuclear differentiation, a finding that further highlights these proteins - and this ciliate - as biological innovators.

A Dynamin-Related Protein Required for Nuclear Remodeling in Tetrahymena
Dynamin-related proteins (DRPs) are GTPases that reversibly assemble on cellular membranes [1]. Individual DRPs (here "DRP" includes authentic dynamins) function in fission or tubulation of the plasma membrane, trans-Golgi network, mitochondria, peroxisomes, chloroplasts, and endosomes [1] and in mitochondrial fusion [2]. Many of these functions are widespread; they are present in animals, plan...

متن کاملElucidation of Clathrin-Mediated Endocytosis in Tetrahymena Reveals an Evolutionarily Convergent Recruitment of Dynamin
Ciliates, although single-celled organisms, contain numerous subcellular structures and pathways usually associated with metazoans. How this cell biological complexity relates to the evolution of molecular elements is unclear, because features in these cells have been defined mainly at the morphological level. Among these ciliate features are structures resembling clathrin-coated, endocytic pit...
متن کاملDynamin regulates metaphase furrow formation and plasma membrane compartmentalization in the syncytial Drosophila embryo
The successive nuclear division cycles in the syncytial Drosophila embryo are accompanied by ingression and regression of plasma membrane furrows, which surround individual nuclei at the embryo periphery, playing a central role in embryo compartmentalization prior to cellularization. Here, we demonstrate that cell cycle changes in dynamin localization and activity at the plasma membrane (PM) re...
