Early endosomes are cellular compartments that receive endocytosed materials and sort them for vesicular transport to late endosomes and lysosomes, as well as for recycling material to the plasma membrane. Early endosome antigen 1 (EEA1) is an early endosomal protein that contains an N-terminal zinc finger motif, a cys-rich C-terminal metal-binding finger, and multiple sites for N-glycosylation, phosphorylation, and N-myristoylation. Expression of EEA1 mRNA is observed in skeletal muscle, heart, brain, lung, liver, and pancreas. Immunoblot analysis shows that EEA1 is a 180-kDa protein localized in membrane and cytosolic fractions. Immunofluorescence microscopy shows that EEA1 colocalizes with transferrin and with RAB5 in early endosomes, but not with RAB7 in late endosomes.

Western blot of adult mouse brain tissue lysate. The blot was probed with mouse monoclonal anti-EEA1 antibody at 1:500 (lane 1) or 1:1000 (lane 2).

Immunocytochemical labeling of EEA1 in paraformaldehyde-fixed and NP40-permeabilized A7r5 cells. The cells were labeled with mouse monoclonal EEA1 (EM3471). The antibody was detected using goat anti-mouse DyLight® 488.

Clone M347 was generated from a recombinant protein corresponding to amino acid residues in the N-terminal region of human EEA1. This sequence has high homology to similar regions in rat and mouse EEA1.

This antibody detects a 180 kDa* protein corresponding to the apparent molecular mass of EEA1 on SDS-PAGE immunoblots of adult mouse brain. In immunocytochemistry, anti-EEA1 specifically stains endosomal vesicles.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.
