Protein production is the biotechnological process of generating a specific protein. It is typically achieved by the manipulation of gene expression in an organism such that it expresses large amounts of a recombinant gene .
The researchers named these structures processing bodies or "P bodies". During this time, many descriptive names were used also to identify the processing bodies, including "GW-bodies" and "decapping-bodies"; however "P-bodies" was the term chosen and is now widely used and accepted in the scientific literature.

An example that reveals the interaction of the multiple negative and positive feedback loops is the activation of cyclin-dependent protein kinases, or Cdks14. Positive feedback loops play a role by switching cells from low to high Cdk-activity. The interaction between the two types of loops is evident in mitosis.
When G 2 is completed, the cell enters a relatively brief period of nuclear and cellular division, composed of mitosis and cytokinesis, respectively. After the successful completion of mitosis and cytokinesis, both resulting daughter cells re-enter G 1 of interphase. In the cell cycle, interphase is preceded by telophase and cytokinesis of the ...
Fluorescence microscopy micrographs, showing the endogenous human protein Mad1 (one of the spindle checkpoint components) in green, along the different phases in mitosis; CENP-B, in red, is a centromeric marker, and DAPI (in blue) stains DNA. The first protein to be assembled on the kinetochore is CENP-A (Cse4 in Saccharomyces cerevisiae).
Survivin, also called baculoviral inhibitor of apoptosis repeat-containing 5 or BIRC5, is a protein that, in humans, is encoded by the BIRC5 gene. [5] [6] Survivin is a member of the inhibitor of apoptosis (IAP) family. The survivin protein functions to inhibit caspase activation, thereby leading to negative regulation of apoptosis or ...
It also plays a role in mitotic spindle assembly through its interaction with nuclear mitotic apparatus protein 1 (NuMa), therefore allowing the necessary bipolar orientation. In the absence of TNKs, mitosis arrest is observed in pre-anaphase through Mad2 spindle checkpoint. TNKs can also PARsylate Mcl-1L and Mcl-1S and inhibit both their pro ...
Designated for motivated students with a command of standard English, an interest in exploring and analyzing challenging classical and contemporary literature, and a desire to analyze and interpret dominant literary genres and themes, it is often offered to high school seniors and the other AP English course, AP English Language and Composition, to juniors.
