A modified recombinant nonapeptide (LMLGEFLKL) derived from the anti-apoptosis protein survivin with potential immunopotentiating and antineoplastic activities. Upon administration, survivin Sur1M2 peptide vaccine may elicit humoral and cellular immune responses against survivin-expressing cancers, resulting in decreased tumor cell proliferation and tumor cell death. The survivin protein inhibits caspase activation and apoptosis; it is undetectable in normal adult tissues but is expressed by several human cancers including lung, colon, breast, pancreas, and prostate cancer as well as hematopoietic malignancies and skin cancers. Check for active clinical trials using this agent. (NCI Thesaurus)
