Transgene: Tg(Prnp-ITM2B/APP695*42)A12Emcg  Location: unknown  
Strain of Origin:  (C3H x C57BL/6)F1 x C57BL/6

Mutation:    Insertion
Mutation detailsThe transgene was generated with a mouse prion promoter upstream of a BRI-Abeta42 fusion construct, containing a cDNA sequence from human type 2 transmembrane protein (BRI or ITM2B) fused in-frame with a "wildtype APP695" cDNA sequence encoding amyloid-beta42 (Abeta42) at the furin-like cleavage site; the C-terminal 23 amino acid ABri peptide of BRI was replaced with the Abeta42 sequence. Mice from the founder with the highest Abeta42 plasma levels, line BRI-Abeta42A (12e) were donated to the Jackson Laboratory. Transgenic fusion protein expression approximates levels of endogenous mouse APP expression and is expressed in patterns characteristic of the Prnp promoter, with highest expression in cerebellar granule cells and hippocampus. Full length Abeta fusion protein is most highly expressed with processed Abeta42 peptide expressed at lower levels (J:101023, J:120781)
