Disease

[NCOA2_HUMAN] Note=Chromosomal aberrations involving NCOA2 may be a cause of acute myeloid leukemias. Inversion inv(8)(p11;q13) generates the KAT6A-NCOA2 oncogene, which consists of the N-terminal part of KAT6A and the C-terminal part of NCOA2/TIF2. KAT6A-NCOA2 binds to CREBBP and disrupts its function in transcription activation.

Function

[RORG_HUMAN] Possible nuclear receptor for hydroxycholesterols, the binding of which strongly promotes coactivators recruitment. Essential for thymopoiesis and the development of several secondary lymphoid tissues, including lymph nodes. Involved in lineage specification of uncommitted CD4(+) T-helper cells into Th17 cells. Regulate the expression of several components of the circadian clock. [NCOA2_HUMAN] Transcriptional coactivator for steroid receptors and nuclear receptors. Coactivator of the steroid binding domain (AF-2) but not of the modulating N-terminal domain (AF-1). Required with NCOA1 to control energy balance between white and brown adipose tissues.^[1]

Publication Abstract from PubMed

The retinoic acid-related orphan receptor gamma (RORgamma) has important roles in development and metabolic homeostasis. Although the biological functions of RORgamma have been studied extensively, no ligands for RORgamma have been identified, and no structure of RORgamma has been reported. In this study, we showed that hydroxycholesterols promote the recruitment of coactivators by RORgamma using biochemical assays. We also report the crystal structures of the RORgamma ligand-binding domain bound with hydroxycholesterols. The structures reveal the binding modes of various hydroxycholesterols in the RORgamma pocket, with the receptors all adopting the canonical active conformation. Mutations that disrupt the binding of hydroxycholesterols abolish the constitutive activity of RORgamma. Our observations suggest an important role for the endogenous hydroxycholesterols in modulating RORgamma-dependent biological processes.
