Biolegend, 634504, Alexa Fluor® 594 anti-Alix Antibody

Alix (ALG-2-interacting protein X) is an adaptor protein that was first described for its capacity to bind to the calcium-binding protein ALG-2, the expression of which seemed necessary for cell death. The predicted molecular weight is approximately 96 kD. Alix contains an N-terminal Bro1 domain and a C-terminal proline-rich domain (PRD). The PRD contains multiple polyproline motifs, which are potential docking sites for proteins containing SH3 domains, interact with multiple cellular Alix-binding partners that are involved in apoptotic induction, endosomal sorting, and endocytosis. The Bro1 domain interacts with CHMP4b, which is also involved in endosomal sorting.
