Shuttle into the nucleus
In humans, the glycerol phosphate shuttle is primarily found in brown adipose tissue, as the conversion is less efficient, thus generating heat, which is one of the main purposes of brown fat. It is primarily found in babies, though it is present in small amounts in adults around the kidneys and on the back of our necks. The malate-aspartate shuttle is found in much of the rest of the body.

Shuttle into the nucleus
Did you know?
Nuclear transport refers to the mechanisms by which molecules move across the nuclear membrane of a cell. 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, … See more Protein that must be imported to the nucleus from the cytoplasm carry nuclear localization signals (NLS) that are bound by importins. An NLS is a sequence of amino acids that acts as a tag. They are most commonly See more Many proteins are known to have both NESs and NLSs and thus shuttle constantly between the nucleus and the cytosol. In certain … See more Nuclear export roughly reverses the import process; in the nucleus, the exportin binds the cargo and Ran-GTP and diffuses through the pore to the cytoplasm, where the complex dissociates. Ran-GTP binds GAP and hydrolyzes GTP, and the resulting Ran-GDP complex is … See more • Nuclear Transport animations Archived 2009-02-07 at the Wayback Machine • Nuclear Transport illustrations Archived 2009-02-07 at the Wayback Machine See more WebJun 9, 2024 · The nuclear pore complex (NPC) regulates transport of macromolecules into and out of the nucleus.

WebOct 29, 2024 · A model for the nucleocytoplasmic shuttling of ERα, regulated by the importin family. Following cytoplasmic translation, ERα translocates into the nucleus by active transport mediated by importin-α4/β (1). ERα can also shuttle between the nucleus and cytoplasm by passive diffusion (2).
WebMay 15, 1998 · Many proteins need to be imported into the nucleus multiple times, as is the case for proteins which shuttle continuously between nucleus and cytoplasm. In addition, higher eukaryotes have an open mitosis and all not-chromatin-bound nuclear proteins need to be re-imported upon reformation of the nuclear envelope after mitosis. greenwood fort worth obitsWebJul 1, 2005 · To understand the origin of nuclear mature tRNAs, we examined whether tRNAs are imported into the nucleus from the cytosol, using heterokaryon assays ().In S. … foam padding for garage wallWebAug 29, 2007 · Under these conditions, SIRT2 entering into the nucleus is inhibited from binding to Crm1 and blocked from being exported leading to the nuclear sequestration of SIRT2. ...
