Ribosomal RNA Synthesis02:53

Ribosomal RNA Synthesis

15.1K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

Nuclear Protein Sorting01:34

Nuclear Protein Sorting

6.6K
Nuclear protein sorting is the selective trafficking of histones, polymerases, gene regulatory proteins into the nucleus and exporting RNAs and ribosomes to the cytosol. It is a tightly controlled process that regulates gene expression within a cell.
Proteins targeted to the nucleus carry nuclear localization signals or NLS recognized by import receptors in the cytosol. Similarly, proteins with nuclear export signals are recognized by export receptors. Import and export receptors are...

Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

3.4K
Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...

Additional Subnuclear Structures02:10

Additional Subnuclear Structures

5.5K
The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals. 
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles,...

The Nucleolus02:55

The Nucleolus

10.6K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

The Endoplasmic Reticulum01:43

The Endoplasmic Reticulum

22.5K
The endoplasmic reticulum or ER makes up for more than half of the membranes in a cell and accounts for 10% of total cell volume. It is also the primary protein and lipid synthesis factory for most cell organelles, such as the Golgi apparatus, lysosomes, secretory vesicles, and the plasma membrane. Despite being the most extensive and functionally complex subcellular organelle, ER was the last to be discovered. After years of deliberation, Keith Porter and George Palade in the year 1954,...

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Biophysics

Background:

  • The nuclear envelope (NE) is a dynamic structure in mammalian cells.
  • Complex membrane-bounded invaginations, termed nucleoplasmic reticulum (NR), can form within the NE.
  • NR formation occurs during interphase, independent of mitosis.

Purpose of the Study:

  • To explore mechanisms driving the formation of nucleoplasmic reticulum (NR) during interphase.
  • To consider models for the deformation of the interphase nuclear envelope.
  • To review evidence supporting potential roles of NR structures.

Main Methods:

  • Theoretical modeling of membrane deformation.
  • Review of existing experimental evidence.
  • Analysis of NE dynamics during interphase.

Main Results:

  • Models suggest specific biophysical forces can drive NE invagination.
  • Evidence points to distinct pathways for NR formation compared to mitotic reassembly.
  • Potential functions of NR in cellular processes are discussed.

Conclusions:

  • Interphase NE deformation provides a framework for understanding NR biogenesis.
  • Further research is needed to elucidate the precise molecular players and functional significance of NR.
