The function of Ensembl gene identifier ENSG00000043143 (JADE2, jade family PHD finger 2) is as follows. Scaffold subunit of some HBO1 complexes, which have a histone H4 acetyltransferase activity (PubMed:16387653). Acts as an E3 ubiquitin-protein ligase mediating the ubiquitination and subsequent proteasomal degradation of target protein histone demethylase KDM1A (PubMed:25018020). Also acts as a ubiquitin ligase E3 toward itself. Positive regulator of neurogenesis (By similarity). {ECO:0000250|UniProtKB:Q6ZQF7, ECO:0000269|PubMed:16387653, ECO:0000269|PubMed:25018020}.
