Example sentences for: mitotic
How can you use “mitotic” in a sentence? Here are some example sentences to help you improve your vocabulary:
First, net1(7m) and net1(19m') mutants exerted a modest effect on release of Cdc14 from the nucleolus, in that ~40% of cells with long mitotic spindles retained focal localization of Cdc14 and that both net1 phospho-site mutants displayed a modest defect in 'Cdc14 early anaphase release' (FEAR; [ 26 ] ). Second, net1(19m') showed a synthetic growth defect when combined with dbf2-1 or the msd2-1 allele of CDC5 . Third, phosphorylation site mapping of Net1 purified from arrested cdc14-1 cells (WS and SC, unpublished data) revealed that at least one (S231) of the five in vivo phosphorylation sites in the first 341 amino acids was directly phosphorylated by Cdc5 in vitro . Nevertheless, because expression of neither Net1(7m) nor Net1(19m') had a major impact on exit from mitosis, any direct effect of Cdc5 on Net1 appears to be minor, and the requirement for Cdc5 in the release of Cdc14 might arise principally from phosphorylation of other release-promoting proteins.
Experiments using immuno-fluorescence in vertebrate cells are beginning to order the recruitment and timing of incorporation of individual nucleoporins during post-mitotic re-assembly [ 12 13 14 15 ] . Additionally, in vitro assembly studies with Xenopus egg or mitotic cell extracts have revealed several intermediates in NPC assembly and demonstrated a requirement for an intact double nuclear membrane prior to post-mitotic NPC assembly [ 16 17 18 19 ] . The modular nature of the NPC structure has also suggested that subcomplexes of discrete Nups may initially form and provide building blocks for biogenesis.
Biochemical and cell biological experiments indicate that Net1 acts as part of a complex named RENT that tethers Cdc14 to the nucleolus and inhibits Cdc14 phosphatase activity, and that CDC15 and TEM1 are required for the release of Cdc14 from Net1 at the end of mitosis [ 15 16 17 43 ] . Consistent with this notion, both net1 tab 2-1(which encodes a mutant version of Net1 with presumably reduced affinity for Cdc14) and CDC14 TAB 6-1(which encodes a mutant version of Cdc14 with reduced affinity for Tab2/Net1) bypass cdc15Δ [ 15 18 ] . Both net1 tab 2-1and CDC14 TAB 6-1impinge directly on mitotic exit, suggesting that other TAB genes may encode physiological regulators and effectors of the Mitotic Exit Network.
The locations of repeated sequences within the heterochromatin have been studied using in situ hybridization of probes derived from known repeated elements to mitotic chromosomes [ 26, 27].
By counteracting Cdk1-mediated phosphorylations, Cdc14 activates both Hct1/Cdh1, which targets Clb2 for degradation [ 3 4 5 ] , and Swi5, which turns on the transcription of Cdk1 inhibitor Sic1 [ 6 3 ] . Degradation of Clb2 and accumulation of Sic1 act in concert to eliminate mitotic Cdk activity, which is required for exit from mitosis [ 7 ] . Thus, elucidating how Cdc14 is regulated holds the key to understanding how cells exit mitosis.
