WebLaminin is a large (900 kDa) mosaic protein composed of many distinct domains with different structures and functions. Globular and rodlike domains are arranged in an extended four-armed, cruciform shape that is well suited for mediating between distant sites on cells and other components of the extracellular matrix.

WebNov 10, 2024 · Laminins Each LM is a glycoprotein heterotrimer composed of three subunits: an α-, a β- and a γ-chain, with each chain derived from a distinct gene. In humans, there are five α-chain (LAMA1–5), three β-chain (LAMB1–3) and … Laminins are heterotrimeric proteins with a high molecular mass (~400 to ~900 kDa). They contain three different chains (α, β and γ) encoded by five, four, and three paralogous genes in humans, respectively. The laminin molecules are named according to their chain composition. Thus, laminin-511 contains … See more Laminins are a family of glycoproteins of the extracellular matrix of all animals. They are major components of the basal lamina (one of the layers of the basement membrane), the protein network foundation for most cells and organs. … See more In humans, fifteen laminin trimers have been identified. The laminins are combinations of different alpha-, beta-, and gamma-chains. • Five … See more Dysfunctional structure of one particular laminin, laminin-211, is the cause of one form of congenital muscular dystrophy. Laminin-211 is … See more Laminins contain several conserved protein domains. Laminin I and Laminin II Laminins are trimeric molecules; laminin-1 is an alpha1 beta1 gamma1 trimer. It has been suggested that the domains I and II from laminin A, B1 … See more Laminins form independent networks and are associated with type IV collagen networks via entactin, fibronectin, and perlecan. They also bind to cell membranes through integrins and other plasma membrane molecules, such as the dystroglycan glycoprotein … See more Together with other major components of the ECM, such as collagens and fibronectin, laminins have been used to enhance mammalian cell culture, especially in the case of pluripotent … See more • Laminin domain I: all laminin alpha chains (LAMA1, LAMA2, LAMA3, LAMA4, LAMA5) • Laminin domain II: all laminin alpha chains (LAMA1, LAMA2, LAMA3, LAMA4, LAMA5) See more infoexcelgroup

WebMay 15, 2024 · Similarly to fibronectin (another important glycoprotein of the extracellular matrix), laminins form networks and bind to cellular receptors. Defective cell adhesion to laminins results in severe human diseases, such as muscular dystrophies and skin blistering disorders [ 7, 8 ]. WebLaminin This miracle found in our genetic make-up at first is very unassuming. It’s a simple protein molecule and it’s one amongst tens of thousands in our body. When cells organize into...
