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.
