some particularly commonly transcribed genes are physically located near nuclear pores to facilitate the translocation process.
some particularly commonly transcribed genes are physically located near nuclear pores to facilitate the translocation process.
both systems provide structural support for the nuclear envelope and anchoring sites for chromosomes and nuclear pores.
ambos os sistemas dão o suporte estrutural para o envelope nuclear e actuam como pontos de ancoragem para os cromossomas e poros nucleares.
nuclear pores are large protein complexes that cross the nuclear envelope, which is the double membrane surrounding the eukaryotic cell nucleus.
os poros nucleares são grandes complexos de proteínas que atravessam o envoltório nuclear, uma membrana dupla que existe ao redor do núcleo das células eucariontes.
because the nuclear membrane is impermeable to large molecules, nuclear pores are required that regulate nuclear transport of molecules across the envelope.
essa comunicação é realizada pelos poros nucleares que se formam da fusão entre a membrana interna e a externa do envoltório nuclear.
nuclear import depends on the importin binding its cargo in the cytoplasm and carrying it through the nuclear pore into the nucleus.
a importação nuclear depende da importina se ligar à sua carga, no citoplasma, e transportá-la através do poro nuclear até ao núcleo.
the entry and exit of large molecules from the cell nucleus is tightly controlled by the nuclear pore complexes (npcs).
a entrada e a saída de moléculas grandes do núcleo celular é altamente controlado pelos complexos de poros nucleares.
== function ==despite not being fully elucidated, vaults have been associated with the nuclear pore complexes and their octagonal shape appears to support this.
== função ==apesar de não estar completamente esclarecido, as "vaults" têm sido associados aos poros do complexo nuclear e sua forma octogonal parece suportar isso.
==dynamics and regulation=====nuclear transport===the entry and exit of large molecules from the nucleus is tightly controlled by the nuclear pore complexes.
== dinâmica e regulação ===== transporte nuclear ===a entrada e saída de grandes moléculas do núcleo está intimamente controlada pelos complexos de poros nucleares.
