Microtubule-associated protein 2 (MAP2) is a major cytoskeletal protein in neurons belonging to a family of heat stable microtubule-associated proteins. It has 11 conserved PXXP motifs that are ligands for Src homology 3 (SH3) domains. MAP2 contains a microtubule-binding domain (MTBD) near the carboxyl terminus of the molecule.
Synonyms: Anti-MAP 2; Anti-MAP-2; Anti-Microtubule-associated protein 2
Storage: -20C
Application: Anti-MAP2 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: Microtubule-associated protein 2 (MAP2) is majorly involved in maintaining cellular structural integrity, microtubule assembly and stability by interacting with the carboxy-terminal of tubulin and linking other cytoskeletal polymers to it. It acts like a molecular scaffold upon which cytoskeleton-modifying proteins assemble, interact and dissociate in response to neuronal activity. Many proteins like type II regulatory subunit of protein kinase A ( PKA), F-actin, calmodulin and the mitochondrial outer membrane protein porin have been shown to interact with MAP2. Tyrosine kinase FYN binds with and phosphorylates MAP2. This phosphorylation further helps in binding of the Src homology 2 (SH2) domain of growth factor receptor-bound protein 2 (GRB2) to MAP2. In this way, a number of signaling proteins are recruited by it for the pathways involved in central nervous system development.
