What Is Lamin Protein

The two major proteins produced from this gene lamin a and lamin c are made in most of the body s cells.

What is lamin protein.

Lamins line the inside of the nuclear membrane where they provide a platform for the binding of proteins and chromatin and confer mechanical stability. Lamins have elastic and mechanosensitive properties and can alter gene regulation in a feedback response to mechanical cues. There are several different laminins. The lmnagene provides instructions for making several slightly different proteins called lamins.

Laminin is a protein that is part of the extracellular matrix in humans and animals. Laminin has arms that associate with other laminin molecules to form sheets and bind to cells. Lamins are present in all animals but are not found in microorganisms. Lamins also known as nuclear lamins are fibrous proteins in type v intermediate filaments providing structural function and transcriptional regulation in the cell nucleus.

Laminin is defined by the webster medical dictionary as a glycoprotein that is a component of connective tissue basement membrane and that promotes cell adhesion in other words looking at laminin as a kind of glue isn t far from the truth. The lamins are the major architectural proteins of the animal cell nucleus. Laminins are high molecular weight 400 to 900 kda proteins of the extracellular matrix they are a major component of the basal lamina one of the layers of the basement membrane a protein network foundation for most cells and organs the laminins are an important and biologically active part of the basal lamina influencing cell differentiation migration and adhesion.
