Introduction
Recombinant Human CD56/NCAM1 Protein, also known as neural cell adhesion molecule 1, is a glycoprotein that is primarily expressed on the surface of neurons and glial cells in the nervous system. It is encoded by the NCAM1 gene and is involved in various cellular processes such as cell adhesion, migration, and signaling. In this article, we will explore the structure, activity, and applications of this important recombinant protein.
Structure of Recombinant Human CD56/NCAM1 Protein
The recombinant human CD56/NCAM1 protein is a type I transmembrane glycoprotein that belongs to the immunoglobulin superfamily. It is composed of five extracellular domains, a transmembrane domain, and a cytoplasmic domain. The extracellular domains contain six immunoglobulin-like domains (Ig1-Ig6) and five fibronectin type III-like repeats (FnIII1-FnIII5). These domains are responsible for the protein’s adhesive properties and its ability to interact with other molecules. The transmembrane domain anchors the protein to the cell membrane, while the cytoplasmic domain is involved in intracellular signaling.
