Anti-ALPHA-CP3 antibodies are used in antigen-specific immunodetection in biological samples. The target ALPHA-CP3 is a known alias name of the protein poly(rC) binding protein 3, encoded by the PCBP3 gene in humans. This 371-amino acid residue protein is known to be involved in the regulation of gene expression, among other biological processes. It is localized to the cytoplasm of the cell. It is reported to be widely expressed in many tissue types. The term ALPHA-CP3 is another synonym for ALPHA-CP3.
