Function

[HUNIN_HUMAN] Plays a role as a neuroprotective factor. Protects against death induced by multiple different familial Alzheimer disease genes and beta amyloid proteins in Alzheimer disease. Suppresses apoptosis by binding to BAX and preventing the translocation of BAX from the cytosol to mitochondria. Binds to IGFBP3 and specifically blocks IGFBP3-induced cell death Induces chemotaxis of mononuclear phagocytes via FPR2. Reduces the aggregation and fibrillary formation by suppressing the effect of APP on mononuclear phagocytes and acts by competitively inhibiting the access of FPRL1 to APP.^[1] ^[2] ^[3] ^[4] ^[5]

Publication Abstract from PubMed

The NMR solution study of Ser14Gly-humanin (S14G-HN), a 1000-fold more potent derivative of humanin (HN), is reported. HN is 24-residue peptide that selectively suppresses neuronal cell death caused by Alzheimer's disease (AD)-specific insults and offers hope for the development of a cure against AD. In aqueous solution the NMR data show that S14G-HN is a flexible peptide with turn-like structures in its conformational ensemble distributed over an extensive part of its sequence from Pro3 to Glu15. In the more lipophilic environment of 30% TFE, an alpha-helical structure spanning residues Phe6 to Thr13 is identified. Comparison of these findings to the NMR structure of the parent HN and to existing structure-function relationship literature data outlines the important for activity structural features for this class of neuroprotective peptides, and brings forth flexibility as an important characteristic that may facilitate interactions with functional counterparts of the neuroprotection pathway.
