Laminins are the Adhesive Proteins of Basal Lamina00:55

Laminins are the Adhesive Proteins of Basal Lamina

4.3K
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...

Protein Complex Assembly

17.3K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Structural Protein Function

30.6K
Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity.  In bones and teeth, it mineralizes to...

Assembly of Cytoskeletal Filaments

28.5K
Cytoskeletal filaments are polymeric forms of smaller protein subunits. However, individual cytoskeletal filaments may easily disassemble or associate with other similar filaments to form rigid structures. Microfilaments, made of actin monomers, rely on actin-binding proteins to form bundles and create networks of individual actin filaments. Microtubules rely on microtubule-associated proteins (MAPs) to form sturdy cylindrical structures. However, the proteins involved in forming complex...

Area of Science:

  • Cell Biology
  • Structural Biology
  • Molecular Biology

Background:

  • Lamins are nuclear intermediate filament (IF) proteins crucial for maintaining nuclear structure.
  • They are located between the inner nuclear membrane and peripheral chromatin, with a smaller fraction in the nucleoplasm.
  • Lamins and associated proteins participate in vital nuclear activities.

Purpose of the Study:

  • To review the structural aspects of lamin assembly.
  • To discuss the differences between peripheral and nucleoplasmic lamins.
  • To describe the protein complexes formed by lamins.

Main Methods:

  • Literature review of structural biology and cell biology studies.
  • Analysis of existing data on lamin organization and function.
  • Synthesis of information on lamin-associated protein complexes.

Main Results:

  • Lamins form fibrous structures critical for nuclear integrity.
  • Distinct roles and organizations exist for peripheral and nucleoplasmic lamins.
  • Lamins interact with various proteins to form functional complexes.

Conclusions:

  • Understanding lamin organization is key to deciphering laminopathies.
  • Further research into lamin assembly and interactions is needed.
  • This review provides a framework for studying lamin structure-function relationships.
