Anti-HHIP like 2 antibodies are used in the immunodetection of the protein encoded by the HHIPL2 gene. In humans, the canonical protein has a reported length of 724 amino acid residues and a mass of 80.8 kDa. It is known to be a secreted protein. The HHIP like 2 protein is a member of the HHIP protein family. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include HHIP-like protein 2 and hedgehog interacting protein-like 2.
