免疫原
Synthesized peptide derived from human TCF4/TCF7L2
特异性
This antibody detects endogenous levels of TCF4/TCF7L2 at Human, Mouse
组成（Formulation）
Liquid in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide.
纯化工艺（Immunogen）
The antibody was affinity-purified from mouse antiserum by affinity-chromatography using epitope-specific immunogen.
功能
Participates in the Wnt signaling pathway and modulates MYC expression by binding to its promoter in a sequence-specific manner. Acts as repressor in the absence of CTNNB1, and as activator in its presence. Activates transcription from promoters with several copies of the Tcf motif 5'-CCTTTGATC-3' in the presence of CTNNB1. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated by TCF7L2/TCF4 and CTNNB1. Expression of dominant-negative mutants results in cell-cycle arrest in G1. Necessary for the maintenance of the epithelial stem-cell compartment of the small intestine.
基因名称（Gene Name）
TCF7L2 TCF4
蛋白名称
Transcription factor 7-like 2 (HMG box transcription factor 4) (T-cell-specific transcription factor 4) (T-cell factor 4) (TCF-4) (hTCF-4)
细胞定位
Nucleus, PML body . Diffuse pattern. Colocalizes with SUMO1 and PIAS4 in a subset of PML (promyelocytic leukemia) nuclear bodies.
组织表达
Detected in epithelium from small intestine, with the highest expression at the top of the crypts and a gradient of expression from crypt to villus. Detected in colon epithelium and colon cancer, and in epithelium from mammary gland and carcinomas derived therefrom.
