Nuclear lamins are key proteins that stabilize the cell nucleus. This review covers their structure, self-assembly into polymers, and diverse roles in nuclear functions.

Area of Science:

  • Cell Biology
  • Biochemistry
  • Structural Biology

Background:

  • Nuclear lamins form the nuclear lamina, a meshwork supporting the inner nuclear membrane.
  • Lamins are essential for nuclear mechanical stability and organization.
  • They play roles in DNA replication, chromatin organization, and nuclear growth.

Purpose of the Study:

  • To review the current knowledge on nuclear lamin structure and assembly.
  • To highlight the functional roles of nuclear lamins.
  • To emphasize their self-assembly into oligomers and polymers.

Main Methods:

  • Literature review of existing research on nuclear lamins.
  • Analysis of studies on lamin structure and self-assembly.
  • Synthesis of information on lamin functions.

Main Results:

  • Nuclear lamins are intermediate filament proteins crucial for nuclear stability.
  • They self-assemble into distinct oligomeric and polymeric structures.
  • Lamins influence DNA replication, chromatin organization, and nuclear envelope integrity.

Conclusions:

  • Nuclear lamins are fundamental for nuclear structure and function.
  • Their self-assembly properties are central to their roles.
  • Further research is needed to fully elucidate their complex functions.
