Summaries for CTBP1 Gene

Entrez Gene Summary for CTBP1 Gene

  • This gene encodes a protein that binds to the C-terminus of adenovirus E1A proteins. This phosphoprotein is a transcriptional repressor and may play a role during cellular proliferation. This protein and the product of a second closely related gene, CTBP2, can dimerize. Both proteins can also interact with a polycomb group protein complex which participates in regulation of gene expression during development. Alternative splicing of transcripts from this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]

GeneCards Summary for CTBP1 Gene

CTBP1 (C-Terminal Binding Protein 1) is a Protein Coding gene. Diseases associated with CTBP1 include Colon Adenoma and Borna Disease. Among its related pathways are Notch signaling pathway (KEGG) and Signaling by Wnt. GO annotations related to this gene include transcription factor activity, sequence-specific DNA binding and transcription factor binding. An important paralog of this gene is CTBP2.
