SERPINA1 and cancer: The family, called nNIF-related peptides (NRPs), after the first identified peptide (NET-inhibitory factor, nNIF), also consists of cancer-associated SCM recognition, immune defense suppression and serine protease protection peptide (CRISPP) and a 44–amino acid carboxy terminus cleavage fragment of A1AT (α1-antitrypsin), A1ATm358 (Yost et al. 2016).
