Function

ATAD2_HUMAN May be a transcriptional coactivator of the nuclear receptor ESR1 required to induce the expression of a subset of estradiol target genes, such as CCND1, MYC and E2F1. May play a role in the recruitment or occupancy of CREBBP at some ESR1 target gene promoters. May be required for histone hyperacetylation. Involved in the estrogen-induced cell proliferation and cell cycle progression of breast cancer cells.[1]

Publication Abstract from PubMed

The development of ligands for biological targets is critically dependent on the identification of sites on proteins that bind molecules with high affinity. A set of compounds, called FragLites, can identify such sites, along with the interactions required to gain affinity, by X-ray crystallography. We demonstrate the utility of FragLites in mapping the binding sites of bromodomain proteins BRD4 and ATAD2 and demonstrate that FragLite mapping is comparable to a full fragment screen in identifying ligand binding sites and key interactions. We extend the FragLite set with analogous compounds derived from amino acids (termed PepLites) that mimic the interactions of peptides. The output of the FragLite maps is shown to enable the development of ligands with leadlike potency. This work establishes the use of FragLite and PepLite screening at an early stage in ligand discovery allowing the rapid assessment of tractability of protein targets and informing downstream hit-finding.
