Cardiac-specific Nkx2-5 is a member of the NK2 family of homeodomain-containing transcription factors, and its expression and functions overlap with those of GATA4, GATA5, and GATA6 during cardiovascular genesis, especially in the regulation of target gene expression synergistically with GATA4, which justifies screening for Nkx2-5 as a prime candidate gene for idiopathic AF (Atrial Fibrillation). NKX2-5 plays an important role in heart formation and development. Moreover, NKX2-5 not only individually acts in transcriptional regulation, but also interacts with other transcription factors in the early stage of cardiac development.

This gene encodes a homeobox-containing transcription factor. This transcription factor functions in heart formation and development. Mutations in this gene cause atrial septal defect with atrioventricular conduction defect, and also tetralogy of Fallot, which are both heart malformation diseases. Mutations in this gene can also cause congenital hypothyroidism non-goitrous type 5, a non-autoimmune condition. Alternative splicing results in multiple transcript variants.

NKX2-5: Implicated in commitment to and/or differentiation of the myocardial lineage. Acts as a transcriptional activator of ANF in cooperation with GATA4. Interacts with HIPK1 and HIPK2, but not HIPK3. Interacts with the C-terminal zinc finger of GATA4 through its homeobox domain. Also interacts with JARID2 which represses its ability to activate transcription of ANF. Interacts with FBLIM1. Expressed only in the heart. Belongs to the NK-2 homeobox family. 2 isoforms of the human protein are produced by alternative splicing.
