 The N-terminal peptide, also known as diffusible survival evasion peptide, promotes neural cell survival under conditions of severe oxidative stress.A glycosylated form of the N-terminal peptide may be associated with cachexia (muscle wasting) in cancer patients.The C-termial precursor DCD-1L is a 48 residue peptide that shows partial helicity in solution, as evidenced by the determination of its solution structure by NMR and CD-spectroscopy.
