Anti-CDX2, clone CDX2/9338

1 mg/ml in 1X PBS, BSA free, sodium azide free. The intestine-specific transcription factors CDX1 and CDX2 are important for directing intestinal development, differentiation, proliferation and maintenance of the intestinal phenotype. CDX2 protein expression has been seen in GI carcinomas. Anti-CDX2 has been useful to establish GI origin of metastatic adenocarcinomas and carcinoidsand is especially useful to distinguish metastatic colorectal adenocarcinoma from lung adenocarcinoma.However, mucinous carcinomas of the ovary also express CDX2 protein. It limits the usefulness of this marker in the distinction of metastatic colorectal adenocarcinoma from mucinous carcinoma of the ovary. Protein function: Transcription factor which regulates the transcription of multiple genes expressed in the intestinal epithelium. Binds to the promoter of the intestinal sucrase-isomaltase SI and activates SI transcription. Binds to the DNA sequence 5'-ATAAAAACTTAT-3' in the promoter region of VDR and activates VDR transcription. Binds to and activates transcription of LPH. Activates transcription of CLDN2 and intestinal mucin MUC2. Binds to the 5'-AATTTTTTACAACACCT-3' DNA sequence in the promoter region of CA1 and activates CA1 transcription. Important in broad range of functions from early differentiation to maintenance of the intestinal epithelial lining of both the small and large intestine. Binds preferentially to methylated DNA (PubMed:28473536). [The UniProt Consortium]
