Anti-KRTCAP2 antibodies are used in the immunodetection of the protein keratinocyte associated protein 2. In humans, the canonical protein has a reported length of 136 amino acid residues and a mass of 14.7 kDa. Its subcellular localization is in the ER. It is reported to be expressed in skin, heart, placental, liver, skeletal muscle, kidney, pancreas, keratinocytes and dermal fibroblasts. A member of the KRTCAP2 protein family, KRTCAP2 is a known subunit of the oligosaccharyl transferase (OST) complex that catalyzes the initial transfer of a defined glycan (Glc(3)Man(9)GlcNAc(2) in eukaryotes) from the lipid carrier dolichol-pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation. Synonyms for this target antigen include dolichyl-diphosphooligosaccharide--protein glycosyltransferase subunit KCP2, keratinocytes associated protein 2, oligosaccharyl transferase subunit KCP2, and KCP-2. Some KRTCAP2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
