Cuf2 Is a Novel Meiosis-Specific Regulatory Factor of Meiosis Maturation
BACKGROUND Meiosis is the specialized form of the cell cycle by which diploid cells produce the haploid gametes required for sexual reproduction. Initiation and progression through meiosis requires that the expression of the meiotic genes is precisely controlled so as to provide the correct gene products at the correct times. During meiosis, four temporal gene clusters are either induced or rep...
متن کاملEffect of Fibroblastic Growth Factor on Resumption of Meiosis, In Vitro Maturation And Embryo Development of Immature Mouse Oocytes
Purpose: The purpose of this study was to evaluate the effect of fibroblastic growth factor on resumption of meiosis, in vitro maturation of immature mouse oocytes and resulting embryo development with and without basic fibroblastic growth factor-4 (bFGF-4). Materials and Methods: cumulus – oocyte complex (COCs) and germinal vesicle (GV) were obtained from female NMRI mice 46-48 hours after adm...
متن کاملMug27 is a meiosis-specific protein kinase that functions in fission yeast meiosis II and sporulation.
Several meiosis-specific proteins of Schizosaccharomyces pombe play essential roles in meiotic progression. We report here that a novel meiosis-specific protein kinase, Mug27 (also known as Ppk35), is required for proper spore formation. This kinase is expressed by the mug27(+) gene, which is abruptly transcribed after horsetail movement. This transcription is maintained until the second meioti...
متن کاملA meiosis-specific cyclin regulated by splicing is required for proper progression through meiosis.
The meiotic cell cycle is modified from the mitotic cell cycle by having a premeiotic S phase which leads to high levels of recombination, a reductional pattern of chromosome segregation at the first division, and a second division with no intervening DNA synthesis. Cyclin-dependent kinases are essential for progression through the meiotic cell cycle, as for the mitotic cycle. Here we show that...
متن کاملPalmitoylation: A New Regulatory Role in Meiosis
The addition of lipid moieties to a protein can alter its localization, activity, and ability to associate with other proteins within the cell. There are several types of lipid modifications cells can employ on their proteins, but only one of these, palmitoylation (the addition of a palmitate chain), is reversible. This fact has led scientists to conjecture that cells may be able to fine tune t...
