Anti-EPS8 like 3 antibodies are used in the immunodetection of the protein encoded by the EPS8L3 gene. In humans, the canonical protein has a reported length of 593 amino acid residues and a mass of 66.9 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. The EPS8 like 3 protein is a member of the EPS8 protein family. Other names for this target antigen include EPS8-like protein 3, EPS8-related protein 3, epidermal growth factor receptor pathway substrate 8-related protein 3, and epidermal growth factor receptor kinase substrate 8-like protein 3.
