The TCF family of transcription factors are activated by the Wnt-1 and Wingless pathways and are characterized by the presence of a conserved protein motif, the high mobility group (HMG) 1 box, which mediates DNA binding. Several alternative splice variants of TCF-1 have been identified, including TCF-1A, which share a conserved amino terminus and differ in the carboxy terminal sequences. The Wnt mediated signaling pathway induces cytosolic β-catenin binding to TCF proteins within the nucleus, leading to the enhanced expression of the Wnt target genes. The β-catenin-TCF complexes are negatively regμlated by the adenomatous polyposis coli (APC) tumor suppressor protein, which phosphorylates β-catenin and, in turn, increases the degradation of cytosolic β-catenin and inhibits the transcriptional activity of the TCF proteins.\u003c\/p\u003e \n\n\u003cp\u003eCategory: Primary Antibody\u003c\/p\u003e\n\n\u003cp\u003eReactivity: Human, Mouse, Rat\u003c\/p\u003e\n\n\u003cp\u003eHost: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB, IHC, IP, IF\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: Transcription factor 7, TCF-7, T-cell-specific transcription factor 1, T-cell factor 1, TCF-1, TCF7, TCF1\u003c\/p\u003e\n\n\u003cp\u003eClonality: Polyclonal\u003c\/p\u003e\n\n\u003cp\u003eConjugate: Unconjugated\u003c\/p\u003e\n\n\u003cp\u003eModification: Unmodified\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Synthetic peptide, corresponding to amino acids N-terminus of Human TCF-1.\u003c\/p\u003e\n\n\u003cp\u003eDilution: WB: 1:500~1:1000\u003cbr\u003e\nIHC: 1:50~1:200\u003cbr\u003e\nIP: 1:50~1:200\u003cbr\u003e\nIF: 1:100~1:500\u003c\/p\u003e\n\n\u003cp\u003ePurification: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is \u0026gt; 95% (by SDS-PAGE).\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: TCF-1 (F26) polyclonal antibody detects endogenous levels of TCF-1 protein.\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: ~ 42 kDa\u003c\/p\u003e\n\n\u003cp\u003ePathway: Wntβ catenin signaling，\u003c\/p\u003e\n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
