Anti-C1QTNF1 antibodies are used in the immunodetection of the protein C1q and TNF related 1. In humans, the canonical protein has a reported length of 281 amino acid residues and a mass of 31.7 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. C1QTNF1 is known to be involved with the regulation of intracellular calcium and the regulation of gene expression. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include C1q and tumor necrosis factor related protein 1, G protein coupled receptor interacting protein, g protein-coupled receptor-interacting protein, and complement C1q tumor necrosis factor-related protein 1. C1QTNF1 gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. A number of C1QTNF1 antibodies have been mentioned in research publications and have associated citations. ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
