Research notes

  • Combine with module neighbors to test non-redundant roles of KAT2A.
  • Pair phospho/phenotypic readouts with stimulation and inhibitor controls.
  • Validate antibody clone and compartment; include KD/KO controls.

Assay readouts for KAT2A

  • Histone marks (H3K27me3, H3K4me3—ChIP/WB).
  • Enzyme activity or complex IP.
  • Inhibitor/degrader controls (EZH2, HDAC, BRD).
  • RNA-seq or CUT&Tag downstream.

KAT2A 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 KAT2A studies (examples)

  • Tool lines: HeLa, MCF-7, Jurkat, HEK293T—screen by KAT2A expression (CCLE/DepMap).
  • Combine with neighbors (EP300, CREBBP, KAT2B, KAT5) via KD/pharmacology.
  • Overexpression/rescue in HEK293T supports mechanism and IP.
  • Isogenic/CRISPR models separate dependency from bypass.

[2] Cell samples for KAT2A 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 KAT2A 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 KAT2A immunoprecipitation

  • Tagged overexpression: HEK293T FLAG/HA-KAT2A.
  • 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.
