SLC2A4

Solute carrier family 2, facilitated glucose transporter member 4 (SLC2A4)

SLC2A4 is a Hormone binding & transport on the endocrine & hormone axis. Insulin-regulated facilitative glucose transporter, which plays a key role in removal of glucose from circulation. Response to insulin is regulated by its intracellular localization: in the absence of insulin, it is efficiently retained intracellularly within storage compartments… It is indexed under "Transporters for hormones & metabolites (selected)" 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 SLC2A4.
  • 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.

  • Transport: membrane or nuclear transporter substrate uptake.
  • Binding globulins: free vs total hormone fractions.
  • Tissue distribution: liver/kidney expression & drug-interaction context.

SLC2A4 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 SLC2A4 studies (examples)

  • Tool lines: HepG2, HEK293T, MCF-7, HeLa, Caco-2—screen by SLC2A4 expression and pathway context (CCLE/DepMap).
  • Combine with neighbors (SLC2A1, SLC2A2, SLC2A3, SLC16A1) 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 SLC2A4 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 SLC2A4 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 SLC2A4 immunoprecipitation

  • Tagged overexpression: HEK293T FLAG/HA-SLC2A4 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 SLC2A4 can differ in dosage, splicing, and compartmentation—in organoids/PDX, record passage, matrix, and drug history.
