Ltbp4 refers to a protein target that is studied across multiple biological contexts; annotations and nomenclature can vary by species and isoform. This product corresponds to the Mus musculus (Mouse) sequence context, which can be important when comparing homologs or orthologs across model systems. For curated functional annotations, domains, and sequence features, consult primary databases (e.g., UniProt\/NCBI) and the recent literature for the specific organism and isoform.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eMapping pathway dependencies and signaling networks that drive tumor growth and drug resistance.\u003c\/li\u003e \u003cli\u003eDeveloping and benchmarking biomarker assays (e.g., immunoassays or binding reagents) for candidate targets.\u003c\/li\u003e \u003cli\u003eCharacterizing protein variants, domains, or interaction partners relevant to targeted therapeutics and precision oncology.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelevance:\u003c\/strong\u003e Key regulator of transforming growth factor beta (TGFB1, TGFB2 and TGFB3) that controls TGF-beta activation by maintaining it in a latent state during storage in extracellular space.
