SLC1A5

SLC1A5 (SLC1A5)

SLC1A5 is a Glutamine metabolism / transport on the cellular metabolism axis. Validate function and tissue distribution with UniProt and primary literature. It is indexed under "SLCs: glucose, lactate, amino acids (representative)" 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 SLC1A5.
  • Pair metabolic flux with 13C tracing, Seahorse OCR/ECAR, or metabolomics; nutrient withdrawal/refeed controls.
  • Verify antibody clone, compartment, and stimulation; include KD/KO or inhibitor controls.

SLC1A5 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 SLC1A5 studies (examples)

  • Tool lines: HeLa, A549, MCF-7, HEK293T, HepG2—screen by SLC1A5 expression and pathway context (CCLE/DepMap).
  • Combine with neighbors (SLC2A1, SLC16A1, SLC16A3, SLC16A7) 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 SLC1A5 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 SLC1A5 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 SLC1A5 immunoprecipitation

  • Tagged overexpression: HEK293T FLAG/HA-SLC1A5 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 SLC1A5 can differ in dosage, splicing, and compartmentation—in organoids/PDX, record passage, matrix, and drug history.
