basic FUNCTION	playing multiple roles during pattern formation of vertebrate embryos
	involved in epithelial cell differentiation as well as ductal and lobular proliferation of breast cells

CELLULAR PROCESS

nucleotide, transcription

PHYSIOLOGICAL PROCESS

development

PATHWAY

metabolism

signaling

a component

INTERACTION

DNA

RNA

small molecule

protein	KDM4A catalyzed demethylation of H3K9me3 near the IRX2 promoter to activate its transcription
	KDM4A activates IRX2 transcription and the WNT/CTNNB1 signaling to induce cardiac hypertrophy and dysfunction in hypertrophic cardiomyopathy (HCM)
	IRX2 directly binds to the promoter of the early growth response factor 1 (EGR1) and subsequently initiates the transcription of several fibrosis-related genes
	IRX2 exerts negative regulation on the expression of RUVBL1, which is upregulated in Endometrial carcinoma (EC) and associated with a poorer prognosis
