The C17orf67 antibody is a research tool designed to detect the protein encoded by the C17orf67 gene (Chromosome 17 Open Reading Frame 67), a locus initially identified through genomic sequencing but with limited functional characterization. This gene, also known as CCDC47 (Coiled-Coil Domain Containing 47) in some databases, is ubiquitously expressed across human tissues and is implicated in cellular processes such as protein folding, calcium homeostasis, and endoplasmic reticulum (ER) function. The encoded protein is thought to interact with ER-resident chaperones, though its precise molecular mechanisms remain under investigation.

Antibodies targeting C17orf67 are typically produced in immunized host species (e.g., rabbits or mice) using peptide antigens derived from the protein's conserved regions. These antibodies enable applications like Western blotting, immunofluorescence, and immunohistochemistry to localize and quantify the protein in biological samples. Recent studies have explored its potential roles in cancer, with altered expression observed in malignancies such as hepatocellular carcinoma and breast cancer, suggesting involvement in tumor progression or therapy resistance. However, the protein's pathophysiological relevance and biomarker potential require further validation. Commercial C17orf67 antibodies often undergo validation for specificity via knockout/knockdown controls, yet researchers are advised to confirm target specificity in their experimental systems due to occasional cross-reactivity issues. Ongoing research aims to clarify its biological functions and therapeutic implications.
