This is eukaryotic protein synthesis initiation factor 2B (elF2B); the double phosphorylated amidated peptide labeled with 5-FAM at the N-terminal. Dephosphorylation of this peptide by insulin signaling; and glycogen synthase kinase 3 (GSK3) inhibition; leads to its activation. The references below correspond to the single phosphorylated peptide.

[A90;95] Bid BH3 (77-100); mouse- Cat# 62318
This is amino acids 77 to 100 fragment of Bid BH3 modified murine peptide; with Leu90 and Asp95 replaced by Ala. This peptide may serve as a control for the murine peptide Bid BH3 (77-100). It may be also used in mitochondrial and liposomal release assays.

This sequence is developed around the beta-secretase site of Swedish mutation (Asn670; Leu671) of beta-amyloid precursor protein (APP). It is a substrate for the pro-memapsin 2 active site. Beta-secretase; memapsin 2; cleaves APP; which leads ultimately to the onset of Alzheimer's disease. The fluorescence of EDANS is recovered upon cleavage of this FRET peptide substrate by memapsin 2.

This peptide is naturally occurring mutant within the beta-amyloid region of b-amyloid protein precursor (APP). This mutation is associated with severe cerebral amyloid beta-protein angiopathy (CAA) in Iowa kindred. The affected individuals share a missense mutation in APP at position 694. This site corresponds to residue 23 of beta-amyloid peptide resulting in substitution of asparagine for aspartic acid.

[C92;96] Bid BH3 (77-100); mouse- Cat# 62319
This is amino acids 77 to 100 fragment of Bid BH3 modified murine peptide with Gln92 and Glu96 replaced by Cys. This peptide may be employed in mitochondrial and liposomal release assays.
