Description

UASt regulatory sequences drive expression of the Hsap\LAMB1 open reading frame (amplified from the IOH26807 clone), mutated to carry a N1750Kfs*4 change, a pathogenic variant associated with LAMB1-related leukoencephalopathy. The coding sequence is tagged at the C-terminal end with three copies of Tag:HA. The human ORF is flanked by a pair of incompatible FRT sites (FRT5 and FRT2), which allows for future in vivo exchange of either the promoter or tag sequence.
