LGALS4 and autosomal dominant cerebellar ataxia: We have generated several Gal4-UAS model lines that express human SCA disease proteins (Tsou et al. 2015, 2016; Johnson et al. 2019; Prifti et al. 2023), leveraging a cloning strategy that yields a single-copy, phiC31-dependent insertion into the same attp2 integration site, in the same orientation, on the third Drosophila chromosome (Groth et al. 2004).
