I ate 2 bags of "fang bian mian"... for breakfast and a big meat with rice for lunch, with one potato for fruit. That is too much for me.
~~~ eeeeeerr, happying~~

Nuclear lamina
From http://en.wikipedia.org/wiki/Nuclear_lamina
Jump to: navigation, search
The nuclear lamina is a dense, ~ 30 to 100 nanometers thick, fibrillar network composed of intermediate filaments made of lamin that lines the inner surface of the nuclear envelope in animal cells. At the onset of mitosis, a certain cyclin-dependent kinase complex (Cdk1 and cyclin B in mammals) phosphorylates the lamins, causing them to undergo a conformational change that triggers the disassembly of the nuclear envelope. After the chromosomes have migrated to each pole, the lamins are dephosphorylated, allowing them to begin to reform the nuclear lamina. Initially the lamina reassembles directly on the outer surface of the condensed chromosomes by binding to proteins which associate the condensed DNA, thus excluding all cytoplasmic proteins from the newly forming intranuclear space. The lamins also bind to lamin receptor proteins embedded in the membrane of the endoplasmic reticulum (the ER membrane is continuous with the nuclear envelope). This allows the nuclear envelope to reform around each of the chromosomes. As the chromosomes unwind, their individual coatings of ER membrane merge with one another to form a single nuclear envelope supported by the nuclear lamina. Even during interphase the lamins maintain interactions with DNA binding proteins or DNA itself, especially with heterochromatin which tends to cluster at the surface of the nuclear lamina.

tp53 (formerly p53; aphosphorylated protein of molecular mass 53kd)
which one is former? tp53 or p53?
:confused: :confused:

zhangheng1020UID: 2130513

it is the same!

p53, also known as protein 53 (TP53), is a transcription factor that regulates the cell cycle and hence functions as a tumor suppressor. It is important in multicellular organisms as it helps to suppress cancer. p53 has been described as "the guardian of the genome", "the guardian angel gene", or the "master watchman", referring to its role in conserving stability by preventing genome mutation.[1]

The name p53 is in reference to its apparent molecular mass: it runs as a 53 kilodalton (kDa) protein on SDS-PAGE. Its theoretical molecular mass, based on the sum of its amino acid residues, is in fact only 43.7 kilodalton. This difference is due to the high number of amino-acid proline in the p53 protein. This leads to an aberrant migration on SDS-PAGE. This observation is also found for p53 from other species, such as rodents, frogs, and fish.

p53 is the former name of tp53

they r the same thing
tumor protein 53
it stablize DNA and stop its endless replication, which may cause cancer

tell me those are belong to the PHD`s curriculum~
