EDEM1

EDEM1 (EDEM1)

EDEM1 is a UPR sensor / chaperone on the ER stress signaling axis. Validate with UniProt and literature. Indexed under "Chaperones & ERAD" for antibodies and assay guidance.

Research notes

  • Combine with module neighbors to test non-redundant roles of EDEM1.
  • Pair phospho/phenotypic readouts with stimulation and inhibitor controls.
  • Validate antibody clone and compartment; include KD/KO controls.

  • XBP1s splicing or protein.
  • Cleaved ATF6(N) fragment.
  • BiP/GRP78 chaperone induction.

EDEM1 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 EDEM1 studies (examples)

  • Tool lines: HeLa, HEK293T, MCF-7, HepG2—screen by EDEM1 expression (CCLE/DepMap).
  • Combine with neighbors (HSPA5, HSP90B1, CANX, CALR) via KD/pharmacology.
  • Overexpression/rescue in HEK293T supports mechanism and IP.
  • Isogenic/CRISPR models separate dependency from bypass.

[2] Cell samples for EDEM1 Western blot

  • Whole-cell lysates; phosphatase inhibitors for phospho blots.
  • Optimize stimulation time courses per ligand/stress.
  • Controls: KD/KO or inhibitors.
  • BCA normalization; subcellular fractionation when needed.

[3] Tissue samples for EDEM1 Western blot

  • Matched tumor/adjacent frozen tissues.
  • Mouse models—mind species cross-reactivity.
  • Primary cells/PDCs when approved.
  • FFPE needs specialized extraction; frozen preferred for phospho.

[4] Cell samples for EDEM1 immunoprecipitation

  • Tagged overexpression: HEK293T FLAG/HA-EDEM1.
  • Endogenous IP: high-expression lines.
  • Stimulation enriches interactions.
  • Controls: isotype IgG, empty vector, KO.

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

Models & genetics note

Overexpression vs endogenous EDEM1 can differ in dosage, splicing, and compartmentation.
