nuclear pore complex — a nuclear pore (q.v.) and its associated glycoproteins, which regulates transport between the nucleus and the cytoplasm. It has a diameter of approximately 80–100 nm and is composed of three stacked, octagonally symmetric, ringlike arrays of… … Medical dictionary

Nuclear localization sequence — A nuclear localization signal or sequence (NLS) is an amino acid sequence which tags a protein for import into the cell nucleus by nuclear transport. Typically, this signal consists of one or more short sequences of positively charged lysines or… … Wikipedia
Nuclear transport — The entry and exit of large molecules from the cell nucleus is tightly controlled by the nuclear pore complexes (NPCs). Although small molecules can enter the nucleus without regulation,[1] macromolecules such as RNA and proteins require… … Wikipedia
Nuclear localization signal — A nuclear localizing sequence (NLS) is an amino acid sequence which acts like a tag on the exposed surface of a protein. This sequence is used to target the protein to the cell nucleus through the Nuclear Pore Complex and to direct a newly… … Wikipedia
Nuclear envelope — Human cell nucleus A nuclear envelope (NE) (also known as the perinuclear envelope, nuclear membrane, nucleolemma or karyotheca) is a double lipid bilayer that encloses the genetic material in eukaryotic cells. The nuclear envelope also serves as … Wikipedia
Nuclear dots — ND10s in human embryonic lung cells Nuclear dots (Aliases: Nuclear bodies , nuclear domains , PML bodies ) are punctate structures found in the nucleus of certain cells. Nuclear bodies (NBs) were first seen as prominent interchromatin structures… … Wikipedia
Nuclear export signal — A nuclear export signal (NES) is a short amino acid sequence of 4 hydrophobic residues in a protein that targets it for export from the cell nucleus to the cytoplasm through the nuclear pore complex using nuclear transport. It has the opposite… … Wikipedia
Pore nucléaire — Les pores nucléaires sont de grands complexes protéiques (poids moléculaire estimé à 125 000 kDa) traversant l enveloppe nucléaire qui est une double membrane entourant le noyau des cellules eucaryotes. Les pores nucléaires permettent les… … Wikipédia en Français
nuclear pores — small octagonal openings in the nuclear envelope at sites where the two nuclear membranes are in contact and through which transport between the nucleus and the cytoplasm occurs; the pore and the associated structures embedded in its rim form the … Medical dictionary
