Protein phosphatases at the nuclear envelope
The nuclear envelope (NE) is a unique topological structure formed by lipid membranes (Inner and Outer Membrane: IM and OM) interrupted by open channels (Nuclear Pore complexes). Besides its well-established structural role in providing a physical separation between the genome and the cytoplasm and regulating the exchanges between the two cellular compartments, it has become quite evident in re...
متن کاملDynein at the nuclear envelope.
Most cellular organelles are posi tioned through active transport by motor proteins. this is espe cially important during cell division, a time when the organelles and genetic content need to be divided equally between the two daughter cells. although individual proteins can attain their correct location by diffusion, larger structures are usually posi tioned through active transport by moto...
متن کاملThe function of the nuclear envelope in nuclear protein accumulation
The mechanism by which proteins accumulate in the cell nucleus is not yet known. Two alternative mechanisms are discussed here: (a) selective unidirectional entry of karyophilic proteins through the nuclear pores, and (b) free diffusion of all proteins through the nuclear pores and specific binding of nuclear proteins to nondiffusible components of the nucleoplasm. We present experiments design...
