Technical Data
CDX2 (Homeobox Protein CDX-2, CDX-3, Caudal-type Homeobox Protein 2, CDX3)
CDX2 is a caudal-type homeobox domain-containing transcription factor, important in the development and differentiation of the intestines.It is a part of a regulatory network that orchestrates a developmental program of proliferation, morphogenesis, and gene expression in the intestinal epithelium. It has 311aa and its homeodomain is a 60-aamotif containing a sequence-specific DNA binding domain. The human CDX2 gene is localized to chromosome 13q12-13. The protein has been shown to positively regulate genes expressed in the small intestine such as sucraseisomaltase, lactase and phospholipase A. CDX2 has been implicated in disorders involving abnormal intestinal differentiation and neoplasia. It is also a sensitive and specific marker for colorectal adenocarcinoma, although its expression is decreased among higher grade and stage tumors, and it is not invariably present in metastases from positive primaries.
