SLC25A18 Knockout Huh-7 Cell Line

The choice depends on whether you are studying SLC25A18 (glutamate carrier 2, GC2)'s role as a mitochondrial glutamate transporter — distinct from but functionally related to GC1 (SLC25A22). The Knockout line is appropriate for asking whether GC2 is required for mitochondrial glutamate import, with the caveat that GC2 has lower transport activity than GC1 and more restricted tissue expression (particularly brain). Overexpression is useful for testing transport activity in heterologous systems and for paralog-specific functional studies. For glutamate transporter family research, the EDITGENE SLC25A18 Knockout in Huh-7 enables study of GC2-specific functions in a hepatocellular context. SLC25A22 (GC1) paralog expression should be assessed given functional overlap. Rescue with wild-type GC2 enables structure-function characterization and substrate scope studies.

Primary applications: • Mitochondrial glutamate transport: in vitro glutamate flux assays to characterize GC2 transport activity. • GC1/GC2 paralog studies: combined analysis with SLC25A22 to dissect family-specific functions in glutamate metabolism. • Mitochondrial bioenergetics: Seahorse-based glutamate-supported respiration to assess GC2's metabolic contribution. • Substrate specificity: comparative transport of glutamate analogs to refine substrate scope. EDITGENE recommends this model for researchers investigating mitochondrial glutamate carrier family biology and GC1/GC2 functional specialization.

Yes. GC2 rescue experiments require attention to paralog considerations: • Construct design: use a codon-modified SLC25A18 sequence with a small C-terminal tag (FLAG, HA). GC2 has the SLC25 canonical architecture. • Mitochondrial localization validation: confirm mitochondrial inner membrane localization before functional assays. • GC1 paralog considerations: rescue interpretation should account for SLC25A22 (GC1) expression — combined GC1/GC2 functional analysis may be needed. • Functional readout: rescue should restore mitochondrial glutamate transport activity and glutamate-supported respiration where relevant. Huh-7 transduces efficiently with lentivirus and supports stable rescue line generation.
