	intracellular,nuclear envelope

basic FUNCTION	oxidizing retinaldehyde involved in retinoic acid biogenesis
	RDH10 and ALDH1A2 are critical for RA biosynthesis in the embryo
	ALDH1A2 was predicted to be equally important in RA formation as ALDH1A1
	ALDH1A2 is involved in the regulation of chemoresistant cancer stem cells (CSCs) properties in neuroblastoma
	is essential for the synthesis of retinoic acid from vitamin A

INTERACTION

DNA

RNA

small molecule	cofactor, nucleotide,
	DADP
	NAD

protein	is a direct transcriptional target of WT1 in epicardial cells
	is a direct target of HOXA13
	expression of ALDH1A2 gene is known to be regulated by RA itself, suggesting that the main regulation of the ALDH1A2 activity level is transcriptional
	ALDH1A2 suppresses epithelial ovarian cancer cell proliferation and migration by downregulating STAT3
