ABCG4 (ABCG4)
ABCG4 is a ABC efflux & membrane transport on the transmembrane transport axis. Validate function and tissue distribution with UniProt and primary literature. It is indexed under "ABC transporter superfamily (major members)" on our pathway page for antibodies, inhibitors, and assay guidance.
| Type / example | Domain / context (brief) |
|---|---|
| Expression context | Tissue/cell-type–dependent expression |
| Rare variants | Sporadic variants—require functional validation |
| Pathway coupling | Co-occurs with neighboring nodes on the hub |
Naming and prevalence vary by cohort and assay—annotate clinically with COSMIC, ClinVar, OncoKB, and datasheets; research context only.
Examples below reflect common literature and public resources (e.g., CCLE, DepMap)—validate genotypes, expression, and passage in your own stocks before committing assays.
Human tissues and primary cells require ethics/IRB approval; tumors are heterogeneous—record histotype, site, and preservation conditions.
Overexpression vs endogenous ABCG4 can differ in dosage, splicing, and compartmentation—in organoids/PDX, record passage, matrix, and drug history.
Adds ABCG4 keyword bias atop the 跨膜转运 antibody pool—if sparse, use presets above or global search.
This content supports research reagents and pathway education—not medical advice. Annotate mutations, drug indications, and protocols with authoritative databases, datasheets, and institutional oversight.
