Summaries for CTBP2 Gene

Entrez Gene Summary for CTBP2 Gene

  • This gene produces alternative transcripts encoding two distinct proteins. One protein is a transcriptional repressor, while the other isoform is a major component of specialized synapses known as synaptic ribbons. Both proteins contain a NAD+ binding domain similar to NAD+-dependent 2-hydroxyacid dehydrogenases. A portion of the 3' untranslated region was used to map this gene to chromosome 21q21.3; however, it was noted that similar loci elsewhere in the genome are likely. Blast analysis shows that this gene is present on chromosome 10. Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Feb 2014]

GeneCards Summary for CTBP2 Gene

CTBP2 (C-Terminal Binding Protein 2) is a Protein Coding gene. Diseases associated with CTBP2 include Retinitis Pigmentosa 14 and Congenital Stationary Night Blindness. Among its related pathways are Endometrial cancer and Notch signaling pathway (KEGG). Gene Ontology (GO) annotations related to this gene include chromatin binding and transcription corepressor activity. An important paralog of this gene is CTBP1.

UniProtKB/Swiss-Prot for CTBP2 Gene

  • Corepressor targeting diverse transcription regulators. Functions in brown adipose tissue (BAT) differentiation (By similarity).

  • Isoform 2 probably acts as a scaffold for specialized synapses.
