Summaries for TBX20 Gene

Entrez Gene Summary for TBX20 Gene

  • This gene encodes a T-box family member. The T-box family members share a common DNA binding domain, termed the T-box, and they are transcription factors involved in the regulation of developmental processes. This gene is essential for heart development. Mutations in this gene are associated with diverse cardiac pathologies, including defects in septation, valvulogenesis and cardiomyopathy. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009]

GeneCards Summary for TBX20 Gene

TBX20 (T-Box 20) is a Protein Coding gene. Diseases associated with TBX20 include Atrial Septal Defect 4 and Patent Foramen Ovale. Among its related pathways are Heart Development and Cardiac Progenitor Differentiation. Gene Ontology (GO) annotations related to this gene include DNA binding transcription factor activity and RNA polymerase II transcription factor binding. An important paralog of this gene is TBX15.

UniProtKB/Swiss-Prot for TBX20 Gene

  • Acts as a transcriptional activator and repressor required for cardiac development and may have key roles in the maintenance of functional and structural phenotypes in adult heart.
