General description
The gene Early Endosome Antigen 1 (EEA1) encodes for around 1400 amino acid proteins. It is a peripheral membrane protein associated with the cytoplasmic face of early endosomes. It is a 162 kDa autoantigen protein. EEA1 is a dimer, which comprises extensive coiled-coil regions. At its C-terminus, it contains a cysteine-rich zinc-finger-like domain named FYVE domain. This FYVE domain is conserved from yeast to man. FYVE domain is implicated in the specific localization of EEA1 to endosomes.
Immunogen
synthetic peptide corresponding amino acid residues 24-40 of human EEA1 with C-terminal added cysteine, conjugated to KLH. The corresponding sequence is identical in mouse.
Application
Anti-Early Endosomal Antigen 1 (N-terminal) antibody produced in rabbit has been used in immunoblotting and immunofluorescence.
Biochem/physiol Actions
Early Endosomal Antigen 1 (EEA1) localization in endosomes is implicated in subacute systemic lupus erythematosus. Endosomal targeting of EEA1 also requires its binding to the active form of the small GTPase Rab5. The binding of EEA1 to phosphatidylinositol 3 phosphate (PtdInsP) and rabaptin-5 (Rab5)-GTP is essential for the localization and function of EEA1 in endocytic membrane fusion. Anti-EEA1 may be used as an early endosome marker.
