SLC6A4

Sodium-dependent serotonin transporter (SLC6A4)

SLC6A4 is a Adrenal medulla catecholamine on the endocrine & hormone axis. Serotonin transporter that cotransports serotonin with one Na(+) ion in exchange for one K(+) ion and possibly one proton in an overall electroneutral transport cycle. Transports serotonin across the plasma membrane from the extracellular compartment to the cytosol thus limiting … It is indexed under "Adrenal medulla catecholamine synthesis & turnover" on our pathway page for antibodies, inhibitors, and assay guidance.

Research notes

  • Combine with other genes in the same hub block via genetics or pharmacology to test non-redundant roles of SLC6A4.
  • For nuclear receptors pair ligands, co-regulators, and reporter assays; for membrane receptors note GPCR/RTK downstream and desensitization.
  • Verify antibody clone, phospho-site, and stimulation; include KD/KO or inhibitor controls.

Assay readouts for SLC6A4

  • Catecholamines: SLC6A4 in NE/epinephrine synthesis or secretion.
  • PC-12 / chromaffin: ACh or glucocorticoid differentiation.
  • Tyrosine hydroxylase / DOPA pathway enzyme activity.
  • Stress models: sympatho-adrenal medullary axis.

SLC6A4 experimental notes

Examples below reflect common literature and public resources (e.g., CCLE, DepMap)—validate genotypes, expression, and passage in your own stocks before committing assays.

[1] Cell lines commonly used for SLC6A4 studies (examples)

  • Tool lines: PC-12, SK-N-SH, HEK293T, AtT-20, H295R—screen by SLC6A4 expression and pathway context (CCLE/DepMap).
  • Combine with neighbors (TH, DDC, DBH, PNMT) via KD/pharmacology to test non-redundancy.
  • Overexpression/rescue in HEK293T supports mechanism and IP workflows.
  • Isogenic/CRISPR models separate pathway dependency from bypass survival.

[2] Cell samples for SLC6A4 Western blot

  • Whole-cell lysates—optimize RIPA/NP-40 per antibody; phosphatase inhibitors for phospho blots.
  • Stimulation: serum starvation ± insulin/EGF or amino-acid withdrawal/refeed as relevant.
  • Controls: siRNA/shRNA, CRISPR KO, or inhibitors to validate band specificity.
  • Loading: BCA normalization; subcellular fractionation when needed.

[3] Tissue samples for SLC6A4 Western blot

  • Matched tumor/adjacent frozen tissues after pathology review.
  • Mouse GEMM or xenografts—mind species antibody cross-reactivity.
  • Primary cells/PDCs when ethically approved.
  • FFPE needs specialized extraction; frozen tissue preferred for phospho work.

[4] Cell samples for SLC6A4 immunoprecipitation

  • Tagged overexpression: HEK293T FLAG/HA-SLC6A4 for complex capture.
  • Endogenous IP: high-expression lines; often ≥1–5×10⁶ cells per IP.
  • Stimulation: ligand or nutrient treatments enrich interactions—pilot time courses.
  • Controls: isotype IgG, empty vector, KD/KO negatives.

Human tissues and primary cells require ethics/IRB approval; tumors are heterogeneous—record histotype, site, and preservation conditions.

Models & genetics note

Overexpression vs endogenous SLC6A4 can differ in dosage, splicing, and compartmentation—in organoids/PDX, record passage, matrix, and drug history.
