Description General description Afadin is a cell-cell adherens junction, F-actin binding multidomain protein. This adherens junction protein has two splicing variants: the ubiquitously expressed l-afadin, and the smaller s-afadin, which is abundantly expressed in neural tissues. Afadin associates with E-catenin proteins. S-Afadin is a protein which lacks both the third proline-rich and the F-actin binding regions and is homologous to the human AF-6 (ALL-1 fusion partner from chromosome 6) gene product. Anti-l/s-Afadin is developed in rabbit using a synthetic peptide of rat afadin. Specificity Anti-l/s-Afadin specifically binds to l-afadin and s-afadin by immunoblotting (approximately 200 and 190 kDa respectively). Additional bands may appear in certain extract preparations in western blot assays. The immunizing peptide specifically inhibits the staining of the I/s-afadin bands. The antibody is specific for human, dog, rat, and mouse l/s-afadin. Immunogen synthetic peptide corresponding to rat l/s afadin sequence, amino acids 1163-1179, with N-terminal cysteine added, conjugated to BSA. Application Anti-l/s-Afadin antibody produced in rabbit has been used in : • immunocytochemistry • immunohistochemistry • immunoprecipitation Physical form Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% BSA and 15 mM sodium azide Disclaimer Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals. Biochem/physiol Actions s-Afadin binds to several cytoplasmic proteins such as the small guanosine triphosphatase (GTPase) Ras, the tight junction protein ZO-1 2 and the vinculin binding protein ponsin/ sorbin and SH3 domain containing 1 (SH3P12). In addition, l-afadin also binds through its PDZ several integral membrane components such as the Ca2+ -independent homophilic immunoglobulin-like nectin, the junctional adhesion molecule (JAM)4 and a subset of the EphB receptor protein-tyrosine kinases.
