Anti-PPIAL4 antibodies enable researchers to detect and measure the PPIAL4 antigen in biological samples. This target is a reported synonym of the PPIAL4A gene, which encodes peptidylprolyl isomerase A like 4A. This protein is known to function in protein folding, among other biological roles. The human version of PPIAL4 has a canonical amino acid length of 164 residues and a protein mass of 18.2 kilodaltons. It is reported to be localized in the cytoplasm of cells. PPIAL4 is a member of the Cyclophilin-type PPIase protein family.
