SLC30A3 Knockout Cell Line (HEK293)

The choice depends on whether you are studying SLC30A3 (ZnT3)'s role in vesicular zinc loading or its functions in synaptic zinc and Alzheimer's disease contexts. The Knockout line is the standard tool for asking whether ZnT3 is required for transporting zinc into synaptic vesicles — ZnT3 is principally expressed in zincergic neurons in the hippocampus and cortex. Overexpression is useful for studying vesicular zinc loading in heterologous systems. Important consideration: ZnT3 is primarily neuronal — HEK293 is not the physiological context for ZnT3 function. The EDITGENE Knockout in HEK293 is most useful for in vitro biochemistry, structure-function studies, and as a negative control background for heterologous ZnT3 reconstitution. For physiological synaptic zinc research, neuronal models are more appropriate. Rescue with wild-type or transport-deficient ZnT3 enables mechanistic dissection.

Primary applications: • Heterologous vesicular zinc loading: zinc-sensitive fluorescent probe imaging in vesicular compartments following heterologous ZnT3 expression rescue. • Synaptic zinc biochemistry: in vitro studies of vesicular zinc loading mechanisms in a clean genetic background. • Alzheimer's disease research: studies of ZnT3's reported role in amyloid β interaction and synaptic zinc dynamics. • Structure-function studies: rescue with wild-type or transport-deficient ZnT3 for mechanistic dissection. EDITGENE recommends this model for in vitro ZnT3 biochemistry and structure-function studies. Physiological synaptic zinc research requires neuronal models.

Yes, with heterologous expression considerations: • Construct design: use a codon-modified SLC30A3 sequence with a small C-terminal tag (FLAG, HA). The 6 transmembrane ZnT family architecture must be preserved. • Heterologous expression context: HEK293 does not normally express ZnT3 at functional levels — rescue is a controlled heterologous expression study, useful for biochemical and structure-function research. • Transport-deficient rescue: histidine-rich loop or transmembrane zinc-binding residue mutations enable structure-function studies. • Functional readout: rescue should restore vesicular zinc loading in heterologous expression context, assessed by organelle-targeted zinc sensors. HEK293 transduces efficiently with lentivirus and supports stable rescue line generation.
