Cycle (cyc) is a gene in Drosophila melanogaster that encodes the CYCLE protein (CYC). The Cycle gene ( c yc) is expressed in a variety of cell types in a circadian manner. It is involved in controlling both the sleep-wake cycle and circadian regulation of gene expression by promoting transcription in a negative feedback mechanism.
The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.
The protein is nuclear in the M and G1 phases of the cell cycle and moves to the cytoplasm during S and G2. CDC25B has oncogenic properties, although its role in tumor formation has not been determined. Multiple transcript variants for this gene exist. [6]
The cell cycle is the cycle of events in a cell from one cell division to the next. The main article for this category is Cell cycle . Wikimedia Commons has media related to Cell cycle .
Processes that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.
G 1 phase together with the S phase and G 2 phase comprise the long growth period of the cell cycle cell division called interphase that takes place before cell division in mitosis (M phase). [1] During G 1 phase, the cell grows in size and synthesizes mRNA and protein that are required for DNA synthesis. Once the required proteins and growth ...
CDC34 is a gene that in humans encodes the protein Ubiquitin-conjugating enzyme E2 R1. [5] [6] [7] This protein is a member of the ubiquitin-conjugating enzyme family, which catalyzes the covalent attachment of ubiquitin to other proteins. [8] CDC34 was originally discovered by work in baker's yeast as a gene that is essential for the cell ...
Various genetic studies on Filipinos have been performed, to analyze the population genetics of the various ethnic groups in the Philippines.. The results of a DNA study conducted by the National Geographic's "The Genographic Project", based on genetic testings of Filipino people by the National Geographic in 2008–2009, found that the Philippines is made up of around 53% Southeast Asia and ...
