Anti-peptidyl-prolyl cis/trans isomerase, NIMA-interacting 1 antibodies enable researchers to detect and measure the peptidyl-prolyl cis/trans isomerase, NIMA-interacting 1 antigen in biological samples. This target is a reported synonym of the PIN1 gene, which encodes peptidylprolyl cis/trans isomerase, NIMA-interacting 1. This protein is known to function in the cell cycle and the regulation of cell differentiation, among other biological roles. The human version of peptidyl-prolyl cis/trans isomerase, NIMA-interacting 1 has a canonical amino acid length of 163 residues and a protein mass of 18.2 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in many tissues, such as the bronchus and caudate.
