The gene Early Endosome Antigen 1 (EEA1) encodes for around 1400 amino acid protein. It is a peripheral membrane protein associated with the cytoplasmic face of early endosomes. EEA1 is a autoantigen associated with subacute cutaneous systemic lupus erythematosus and is a coiled-coil protein localized to early endosomes and cytosol.

Recombinant early endosome antigen 1, 162kD

Anti-EEA1 antibody produced in chicken is suitable for immunocytochemistry and western blotting analysis at a dilution of 1:500, for tissue or cell staining at a dilution of 1:200.

Early Endosome Antigen 1 (EEA1) controls vesicle fusion during endocytosis. In neurons, it is involved in recycling of synaptic vesicles and neurotransmitter receptors. Patients with neurological deficits develop EEA1 autoantibodies. Mutation in EEA1 gene leads to susceptibility to diabetes in the Japanese population. Phosphatidylinositol 3-phosphate (PtdIns(3)P) is essential for the localization and function of EEA1.
