Cytology
Description

UAS regulatory sequences drive expression of the 541 amino acid isoform of Psn. The amino acid replacement N157I has been introduced in the coding region, to mimic a N141I change in the human ortholog.

Amino acid change:

N157I | Psn-PA; N157I | Psn-PB; N157I | Psn-PC; N157I | Psn-PD; N157I | Psn-PE

Comment:

Analogous N141I mutation in human PSEN2 implicated in Alzheimer's disease 4; mutation carried on in vitro construct; site of nucleotide substitution in fly gene inferred by FlyBase curator based on reported amino acid change.
