DNA-binding protein GATA-GT2 ; GATA-binding factor 4
Categories
Elisa
Function
Transcriptional activator. Binds to the upstream sequence of the H(+)/K(+)-ATPase beta gene and to a sequence containing the GATA motif. Acts as a transcriptional activator of ANF in cooperation with NKX2-5. Promotes cardiac myocyte enlargement.
Specificity
Natural and recombinant Rat Transcription factor GATA-4
Interacts with the homeobox domain of NKX2-5 through its C-terminal zinc finger. Also interacts with JARID2 which represses its ability to activate transcription of ANF. Interacts with NFATC4 and LMCD1. Forms a complex made of CDK9, CCNT1/cyclin-T1, EP300 and GATA4 that stimulates hypertrophy in cardiomyocytes (By similarity). Interacts with ZNF260.
