Anti-ERVMER34-1 antibodies are used in the immunodetection of the protein endogenous retrovirus group MER34 member 1, envelope. In humans, the canonical protein has a reported length of 563 amino acid residues and a mass of 63.5 kDa. Its subcellular localization is in the cell membrane. It is notably expressed at high level in the placenta and stem cells. It is a member of the Gamma type-C retroviral envelope protein family. Post-translational modifications have been described, including N-glycosylation and protein cleavage. Synonyms for this target antigen include HERV-MER_4q12 provirus ancestral Env polyprotein, Human Endogenous MEdium-Reiteration-frequency-family-34 ORF, LP9056 protein, and endogenous retroviral envelope protein HEMO. Indicated applications for ERVMER34-1 antibodies listed below include Immunohistochemistry.
