== Publication Abstract from PubMed ==
PDCD5-(1-26) is a N-terminal 26-residue fragment of human PDCD5 (programmed cell death 5) protein. PDCD5 is an important novel protein that regulates both apoptotic and non-apoptotic programmed cell death. The conformation of PDCD5 protein is a stable helical core consisting of a triple-helix bundle and two dissociated terminal regions. The N-terminal region is ordered and contains abundant secondary structure. Overexpression and purification of the N-terminal 26-residure fragment, PDCD5-(1-26), was performed in this study to better understand its tertiary structure. The spectroscopic studies using CD and hetero- and homo-nuclear NMR methods determine a stable alpha-helix formed by Asp3-Ala19 of PDCD5-(1-26). The N-terminal residues Asp3-Ala19 of PDCD5 were then affirmed to have the capacity to form a stable alpha-helix independently of the core of the protein. Analysis of the helical peptide of PDCD5-(1-26) indicates that the surface of this well-formed alpha-helix has a unique electrostatic potential character. This may provide an environment for the N-terminal alpha-helix of PDCD5 to serve as an independent functional entity of the protein. The apoptosis activity assay shows that the deletion of the N-terminal alpha-helix of PDCD5 significantly attenuates the apoptosis-promoting effects on HL-60 cells induced by serum withdrawal.

The N-terminal 26-residue fragment of human programmed cell death 5 protein can form a stable alpha-helix having unique electrostatic potential character.,Liu D, Yao H, Chen Y, Feng Y, Chen Y, Wang J Biochem J. 2005 Nov 15;392(Pt 1):47-54. PMID:16083422<ref>PMID:16083422</ref>
