CD9 Recombinant Protein

General Information about CD9 Recombinant Protein

The cluster of differentiation (CD) system is commonly used as a cell marker for immunophenotyping. Different types of cells in the immune system can be identified by surface CD molecules related to cellular immune function. More than 32 unique CD groups and subcategories have been identified. Some CD molecules act as important receptors or ligands for cells, starting a signal cascade and then altering the cell’s behavior. Some CD proteins are not involved in the cell signaling process, but have other functions, such as cell incorporation. CD9 is a member of the transmembrane superfamily 4, also known as the four transmembrane family. CD9 is a cell surface glycoprotein with 4 hydrophobic domains, which is described as complex with integrins and other transmembrane members of superfamily 4. Found on the surface of exosomes. The protein interferes with cell signal transduction events and, therefore, plays a role in regulating cell development and activation, growth and movement. In addition, CD9 appears to play a key role in egg-sperm fusion during mammalian reproduction. CD9 is found in the oocyte membrane and appears to be able to intervene to maintain the normal shape of oocyte microvilli.
