GLP2R

Glucagon-like peptide 2 receptor (GLP2R)

GLP2R is a Membrane hormone receptor (RTK/GPCR) on the endocrine & hormone axis. This is a receptor for glucagon-like peptide 2. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase It is indexed under "Insulin–glucagon–incretin axis" 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 GLP2R.
  • 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 GLP2R

  • Receptor activation: GLP2R ligand-induced p-Tyr / p-AKT / cAMP.
  • GPCR: β-arrestin recruitment and internalization; second-messenger reporters.
  • RTK: insulin/IGF IRS–PI3K axis where applicable.
  • Pharmacology: peptide hormones or small-molecule agonist/antagonist matrices.

GLP2R 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 GLP2R studies (examples)

  • Tool lines: HEK293T, CHO, MIN6, MCF-7, Ba/F3—screen by GLP2R expression and pathway context (CCLE/DepMap).
  • Combine with neighbors (INS, IGF1, IGF2, INSR) 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 GLP2R 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 GLP2R 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 GLP2R immunoprecipitation

  • Tagged overexpression: HEK293T FLAG/HA-GLP2R 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 GLP2R can differ in dosage, splicing, and compartmentation—in organoids/PDX, record passage, matrix, and drug history.
