Disease
[MACD1_HUMAN] A chromosomal aberration involving MACROD1 is found in acute leukemia. Translocation t(11;21)(q13;q22) that forms a RUNX1-MACROD1 fusion protein.
Function
[MACD1_HUMAN] Removes ADP-ribose from glutamate residues in proteins bearing a single ADP-ribose moiety. Inactive towards proteins bearing poly-ADP-ribose. Deacetylates O-acetyl-ADP ribose, a signaling molecule generated by the deacetylation of acetylated lysine residues in histones and other proteins. Plays a role in estrogen signaling. Binds to androgen receptor (AR) and amplifies the transactivation function of AR in response to androgen. May play an important role in carcinogenesis and/or progression of hormone-dependent cancers by feed-forward mechanism that activates ESR1 transactivation. Could be an ESR1 coactivator, providing a positive feedback regulatory loop for ESR1 signal transduction. Could be involved in invasive growth by down-regulating CDH1 in endometrial cancer cells. Enhances ESR1-mediated transcription activity.[1] [2] [3] [4] [5] [6]

Publication Abstract from PubMed
Sirtuins are a family of protein lysine deacetylases, which regulate gene silencing, metabolism, life span, and chromatin structure. Sirtuins utilize NAD(+) to deacetylate proteins, yielding O-acetyl-ADP-ribose (OAADPr) as a reaction product. The macrodomain is a ubiquitous protein module known to bind ADP-ribose derivatives, which diverged through evolution to support many different protein functions and pathways. The observation that some sirtuins and macrodomains are physically linked as fusion proteins or genetically coupled through the same operon, provided a clue that their functions might be connected. Indeed, here we demonstrate that the product of the sirtuin reaction OAADPr is a substrate for several related macrodomain proteins: human MacroD1, human MacroD2, Escherichia coli YmdB, and the sirtuin-linked MacroD-like protein from Staphylococcus aureus. In addition, we show that the cell extracts derived from MacroD-deficient Neurospora crassa strain exhibit a major reduction in the ability to hydrolyze OAADPr. Our data support a novel function of macrodomains as OAADPr deacetylases and potential in vivo regulators of cellular OAADPr produced by NAD(+)-dependent deacetylation.
