Nuclear Lamina

Nuclear Lamina

The nuclear lamina provides mechanical support for the nuclear membrane as well as the nucleus. Furthermore, it plays a role in gene regulation and signaling.

Looking at the image below, we can see that the lamina is attached to the inner nuclear membrane. It is a protein mesh that resides along the perimeter of the nucleus.

Type A, B, and C represent different types of lamins, which are categorized based on "homology in sequence, biochemical properties and cellular localization during the cell cycle."
