It is involved in the regulation of genes that control osmoregulation, ion balance, and epithelial function, particularly in tissues exposed to changing environmental salinity.\u003cp\u003eIn zebrafish, Ostf1 is strongly expressed in the gills, kidney, and other osmoregulatory organs, where it contributes to the adaptation of cells to changes in external ionic and osmotic conditions. Zebrafish Ostf1 is an ortholog of the human OSTF1 gene. Both zebrafish and human proteins share conserved structural features, including domains involved in transcriptional regulation and protein interactions.\u003c\/p\u003e\n\u003cp\u003eFunctionally, Ostf1 acts as an intracellular signaling mediator that is activated in response to hyperosmotic stress. In zebrafish, it has been shown to regulate the expression of ion transporters and channels, including those involved in sodium and chloride balance. It may also contribute to the remodeling of gill epithelium and the function of mitochondrion-rich cells during osmotic adaptation.\u003c\/p\u003e\n\u003cp\u003eOstf1 is also implicated in developmental processes and stress signaling pathways beyond osmoregulation. Because of its conservation and functional importance, zebrafish Ostf1 is widely used in studies of environmental stress physiology, aquaculture research, and basic cell signaling.\u003c\/p\u003e\n\u003c\/div\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).\u003c\/li\u003e\n\u003cli\u003eConsidering isoforms and post-translational regulation when interpreting protein-level changes.\u003c\/li\u003e\n\u003cli\u003eComparing results across species and model systems with matched controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry:\u003c\/strong\u003e map target signal in tissue context and compare regions\/phenotypes.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.\u003c\/li\u003e\n\u003cli\u003eSpecies differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAntibody notes:\u003c\/strong\u003e Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=OSTF1 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=OSTF1 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=OSTF1 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/OSTF1 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=OSTF1+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.5mg\/ml if reconstituted with 0.2ml sterile DI water \/ 100 ug","offer_id":53047329587565,"sku":"RZ1256","price":539.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_0b39d91a-2ec1-474d-bf82-57a94d963064.jpg?v=1772019467","url":"https:\/\/www.ebiohippo.com\/products\/zebrafish-ostf1-antibody-osteoclast-stimulating-factor-1-bha17136451","provider":"BioHippo","version":"1.0","type":"link"}
