SLC37A3 Knockout Cell Line (HEK293)

The choice depends on whether you are studying SLC37A3's role as a putative phosphate/glucose-6-phosphate ER transporter or its emerging functions in lysosomal/ER compartment biology. The Knockout line is appropriate for asking whether SLC37A3 is required for these activities, though its substrate specificity is less defined than its SLC37A4 (G6PT) paralog. Overexpression is useful for testing transport activity in heterologous systems. For SLC37 family research, the EDITGENE Knockout in HEK293 provides a clean background for biochemical and functional studies. SLC37A3 has been reported to participate in lysosomal compartment biology in some contexts. Rescue with wild-type SLC37A3 enables initial functional characterization and substrate scope studies.

Primary applications: • Putative phosphate-sugar transport: in vitro transport assays with candidate substrates to characterize SLC37A3 transport activity. • Subcellular localization: imaging-based analysis of SLC37A3 trafficking and compartment targeting. • Comparative SLC37 family studies: parallel analysis with SLC37A4 to dissect family-specific functions. • Substrate discovery: untargeted metabolomics to identify candidate substrates by detecting altered intracellular metabolite levels. EDITGENE recommends this model for researchers investigating SLC37 family transporter biology and ER/lysosomal phosphate-sugar transport mechanisms.

Yes. SLC37A3 rescue experiments require attention to MFS family architecture: • Construct design: use a codon-modified SLC37A3 sequence with a small C-terminal tag (FLAG, HA). The predicted MFS transporter architecture should be preserved. • Localization validation: confirm subcellular localization (ER, lysosomal, or plasma membrane) by appropriate compartment marker co-staining. • Transport-deficient rescue: conserved MFS family residue mutations enable structure-function studies. • Functional readout: rescue should restore phenotypes identified during knockout phenotype characterization; substrate-specific transport assays test predicted activities. HEK293 transduces efficiently with lentivirus and supports stable rescue line generation.
