Anti-MEGF6 antibodies are used in the immunodetection of the protein multiple EGF like domains 6. In humans, the canonical protein has a reported length of 1541 amino acid residues and a mass of 161.2 kDa. It is known to be a secreted protein. Alternative splicing is reported to yield 2 different isoforms for this protein. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include multiple epidermal growth factor-like domains protein 6, EGF-like protein 3, EGF-like-domain, multiple 3, epidermal growth factor-like protein 3, multiple EGF-like domains protein 6, and EGFL3.
