SLC39A1 Knockout Cell Line (HEK293)

The choice depends on whether you are studying SLC39A1 (ZIP1)'s role in zinc uptake or its specific contributions distinct from other plasma membrane ZIP family members. The Knockout line is appropriate for asking whether ZIP1 is required for cellular zinc influx — ZIP1 is broadly expressed and contributes to zinc uptake in many cell types. Overexpression is useful for testing transport activity and for studying ZIP1's reported tumor-suppressive role in prostate cancer. For ZIP1 research, the EDITGENE Knockout in HEK293 is a standard mechanistic platform. ZIP family redundancy is important — ZIP2, ZIP3, ZIP4 expression should be assessed in parallel given functional overlap. Rescue with wild-type or transport-deficient ZIP1 enables structure-function studies.

Primary applications: • Zinc uptake kinetics: FluoZin-3 imaging or ⁶⁵Zn uptake assays under various external zinc concentrations. • Prostate cancer biology: studies of ZIP1 tumor-suppressive function, given reported ZIP1 downregulation in prostate cancer. • ZIP family redundancy: parallel ZIP2, ZIP3 expression analysis for paralog compensation assessment. • Inhibitor specificity studies: genetic control for ZIP1-selective compounds. EDITGENE recommends this model for researchers investigating zinc uptake biology, ZIP family functional specialization, and prostate cancer-relevant zinc biology.

Yes. ZIP1 rescue experiments require attention to plasma membrane targeting: • Construct design: use a codon-modified SLC39A1 sequence with a small C-terminal tag (FLAG, HA). ZIP1 has 8 transmembrane domains in the canonical ZIP family architecture. • Transport-deficient rescue: histidine-rich loop mutations enable mechanistic studies. • Surface localization validation: confirm plasma membrane localization before functional zinc uptake assays. • Functional readout: rescue should restore zinc uptake activity measured by zinc-sensitive fluorescent probes. HEK293 transduces efficiently with lentivirus and supports stable rescue line generation.
