Rabbit Anti-Mouse Afadin monoclonal antibody for IHC-P, WB. AF-6, also known as afadin, is expressed in a variety of cell types. At least 5 isoforms of this protein are produced by alternative splicing and the 'canonical' sequence is designated as l-afadin. Chromosomal aberration of the MLLT4 gene and tight junctions and Notch signaling pathways cross-communication. This happens through physical interaction with Ras, Notch and Dishevelled, a key Wingless effector. AF-6 also controls integrin-mediated cell adhesion. This is done at least partially by regulating Rap1 activation through recruitment of both SPA-1 and Rap1GTP. These results demonstrate that AF-6 is an important molecule mediating cell-cell adhesion but is also capable of modulating several key signaling pathways.
