The plant nuclear envelope in focus.

چکیده
Recent progress in understanding the plant NE (nuclear envelope) has resulted from significant advances in identifying and characterizing the protein constituents of the membranes and nuclear pores. Here, we review recent findings on the membrane integral and membrane-associated proteins of the key domains of the NE, the pore domain and inner and outer NEs, together with information on protein targeting and NE function.

Recent advances in understanding plant nuclear envelope proteins involved in nuclear morphology.
The nuclear envelope (NE) is a fundamental structure of the nucleus and plays an important role in nuclear morphology through the strict regulation of NE protein function. Beyond its physical barrier function between nucleoplasm and cytoplasm, recent studies of the plant NE have provided novel insights into basic aspects of nuclear morphology as well as cellular organization. In this review, we...
متن کاملFunctional organization and dynamics of the cell nucleus
The eukaryotic cell nucleus enclosed within the nuclear envelope harbors organized chromatin territories and various nuclear bodies as sub-nuclear compartments. This higher-order nuclear organization provides a unique environment to regulate the genome during replication, transcription, maintenance, and other processes. In this review, we focus on the plant four-dimensional nuclear organization...
متن کاملThe nuclear envelope from basic biology to therapy.
The nuclear envelope has long been a focus of basic research for a highly specialized group of cell biologists. More recently, an expanding group of scientists and physicians have developed a keen interest in the nuclear envelope since mutations in the genes encoding lamins and associated proteins have been shown to cause a diverse range of human diseases often called laminopathies or nuclear e...
متن کاملUpdate on the Plant Nuclear Envelope and Nuclear Pore Dynamics of the Plant Nuclear Envelope and Nuclear Pore
The nucleus is the most prominent compartment of any eukaryotic cell and home to its genetic information. The nucleoplasm is surrounded by a double membrane system, the nuclear envelope (NE). The outer nuclear membrane (ONM) and the inner nuclear membrane (INM) are separated by the perinuclear space (or periplasmic space; Hetzer et al., 2005). The lipid bilayer of the ONM is continuous with the...
متن کاملTargeting proteins to the plant nuclear envelope.
The nuclear envelope and the nuclear pore are important structures that both separate and selectively connect the nucleoplasm and the cytoplasm. The requirements for specific targeting of proteins to the plant nuclear envelope and nuclear pore are poorly understood. How are transmembrane-domain proteins sorted to the nuclear envelope and nuclear pore membranes? What protein-protein interactions...
