NKX2-5 (human)

Overview
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. Note: This description may include information from UniProtKB.
