Laminins are the Adhesive Proteins of Basal Lamina00:55

Laminins are the Adhesive Proteins of Basal Lamina

3.4K
Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. alpha, beta, and gamma, coded by five, four, and three paralogous genes, respectively. Laminins are categories based on the compositions of the three chains.
In humans, the five forms of alpha chains are LAMA 1, LAMA 2, LAMA 3, LAMA 4, and LAMA 5. The four forms of beta chains are LAMB 1, LAMB 2, LAMB 3, and LAMB 4. The three forms of gamma...

Mechanism of Lamellipodia Formation

3.1K
Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...

Summary

Nuclear lamins, essential proteins in animals, plants, and unicellular organisms, provide nuclear structure and regulate nuclear activities. Studies in invertebrates like C. elegans and Drosophila advance understanding of lamin assembly, function, and human disease models.
