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

[VDRA_DANRE] Nuclear hormone receptor. Transcription factor that mediates the action of vitamin D3 by controlling the expression of hormone sensitive genes. Regulates transcription of hormone sensitive genes via its association with the WINAC complex, a chromatin-remodeling complex. Plays a central role in calcium homeostasis.^[1] [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.^[2]

Publication Abstract from PubMed

Changing the geminal methyl groups on 1alpha,25 dihydroxyvitamin D3 and its analogs to the deuterio versions generally improves the bioactivity. Derivatives of 1alpha,25 dihydroxyvitamin D3 with two chains emanating at C20, commonly referred to as gemini, are subject to the same phenomenon. Additionally, gemini with different side chains are susceptible to bioactivity differentials where the C17-20 threo configuration usually imparts higher activity than the corresponding erythro arrangement. In an effort to analyze the deuterium effect on gemini with minimal diastereotopic distortion, we synthesized gemini with equal side chains but introduced deuterium diastereospecifically on either chain. We solved the crystal structures of these compounds in the zebra fish zVDR ligand binding domain as complexes with NCoA-2 coactivator peptide and correlated the findings with growth inhibition in a breast cancer cell line.
