WebFunction [ edit] Tumor protein p63 is a member of the p53 family of transcription factors. p63 -/- mice have several developmental defects which include the lack of limbs and other tissues, such as teeth and mammary glands, which develop as a result of interactions between mesenchyme and epithelium. TP63 encodes for two main isoforms by ... WebApr 1, 2014 · Apart from its established role at the p53 promoter, CTCF regulates p53 expression through its physical interaction with Wrap53 RNA. Cells harboring a CTCF mutant in its RBR exhibit a defective p53 response to DNA damage. Moreover, the RBR facilitates CTCF multimerization in an RNA-dependent manner, which may bear directly …
WebCCCTC-binding factor ( CTCF ), an 11- zinc finger factor involved in gene regulation, utilizes different zinc fingers to bind varying DNA target sites. CTCF forms methylation-sensitive insulators that regulate X-chromosome inactivation. Transcriptional repressor CTCFL (this protein) is a paralog of CTCF and appears to be expressed primarily in ...
