macrodomain superfamily; Macrodomains are found in a variety of proteins with diverse cellular functions, as a stand-alone domain or in combination with other domains like in histone macroH2A and some PARPs (poly ADP-ribose polymerases). Macrodomains can recognize ADP-ribose (ADPr) in both its free and protein-linked forms, in related ligands, such as O-acyl-ADP-ribose (OAADPr), and even in ligands unrelated to ADPr. Macrodomains include the yeast macrodomain Poa1 which is a phosphatase of ADP-ribose-1"-phosphate, a by-product of tRNA splicing. Some macrodomains have ADPr-unrelated binding partners such as the coronavirus SUD-N (N-terminal subdomain) and SUD-M (middle subdomain) of the SARS-unique domain (SUD) which bind G-quadruplexes (unusual nucleic-acid structures formed by consecutive guanosine nucleotides). Macrodomains regulate a wide variety of cellular and organismal processes, including DNA damage repair, signal transduction, and immune response.

macrodomain, B-aggressive lymphoma (BAL)-like family; Macrodomains are found in a variety of proteins with diverse cellular functions, as a stand-alone domain or in combination with other domains like in histone macroH2A and some PARPs (poly ADP-ribose polymerases). Macrodomains can recognize ADP-ribose (ADPr) in both its free and protein-linked forms, in related ligands, such as O-acyl-ADP-ribose (OAADPr), and even in ligands unrelated to ADPr. Members of this family show similarity to BAL (B-aggressive lymphoma) proteins, which contain one to three macrodomains. Most BAL family macrodomains belong to this family except for the most N-terminal domain in multiple-domain containing proteins. This family includes the second and third macrodomains of mono-ADP-ribosyltransferase PARP14 (PARP-14, also known as ADP-ribosyltransferase diphtheria toxin-like 8, ATRD8, B aggressive lymphoma protein 2, or BAL2). Most BAL proteins also contain a C-terminal PARP active site and are also named as PARPs. Human BAL1 (or PARP-9) was originally identified as a risk-related gene in diffuse large B-cell lymphoma that promotes malignant B-cell migration. Some BAL family proteins exhibit PARP activity. Poly (ADP-ribosyl)ation is an immediate DNA-damage-dependent post-translational modification of histones and other nuclear proteins. BAL proteins may also function as transcriptional repressors.

Macrodomains can recognize ADP-ribose (ADPr) in both its free and protein-linked forms, in related ligands, such as O-acyl-ADP-ribose (OAADPr), and even in ligands unrelated to ADPr. The macrodomains in this family show similarity to Af1521, a protein from Archaeoglobus fulgidus containing a stand-alone macrodomain. Af1521 binds ADP-ribose and exhibits phosphatase activity toward ADP-ribose-1"-monophosphate (Appr-1"-p). Also included in this family are the N-terminal (or first) macrodomains of BAL (B-aggressive lymphoma) proteins which contain multiple macrodomains, such as the first macrodomain of mono-ADP-ribosyltransferase PARP14 (PARP-14, also known as ADP-ribosyltransferase diphtheria toxin-like 8, ATRD8, B aggressive lymphoma protein 2, or BAL2). Most BAL proteins also contain a C-terminal PARP active site and are also named as PARPs.

Macrodomains can recognize ADP-ribose (ADPr) in both its free and protein-linked forms, in related ligands, such as O-acyl-ADP-ribose (OAADPr), and even in ligands unrelated to ADPr. Members of this family are similar to macroH2A, a variant of the major-type core histone H2A, which contains an N-terminal H2A domain and a C-terminal nonhistone macrodomain. Histone macroH2A is enriched on the inactive X chromosome of mammalian female cells. It does not bind poly ADP-ribose, but does bind the monomeric SirT1 metabolite O-acetyl-ADP-ribose (OAADPR) with high affinity through its macrodomain. This family also includes the ADP-ribose binding macrodomain of the macroH2A variant, macroH2A1.1. The macroH2A1.1 isoform inhibits PARP1-dependent DNA-damage induced chromatin dynamics. The putative ADP-ribose binding pocket of the human macroH2A2 macrodomain exhibits marked structural differences compared with the macroH2A1.1 variant.

macrodomain, Af1521-like family; Macrodomains are found in a variety of proteins with diverse cellular functions, as a stand-alone domain or in combination with other domains like in histone macroH2A and some PARPs (poly ADP-ribose polymerases). Macrodomains can recognize ADP-ribose (ADPr) in both its free and protein-linked forms, in related ligands, such as O-acyl-ADP-ribose (OAADPr), and even in ligands unrelated to ADPr. The macrodomains in this family show similarity to Af1521, a protein from Archaeoglobus fulgidus containing a stand-alone macrodomain. Af1521 binds ADP-ribose and exhibits phosphatase activity toward ADP-ribose-1"-monophosphate (Appr-1"-p). Also included in this family are the N-terminal (or first) macrodomains of BAL (B-aggressive lymphoma) proteins which contain multiple macrodomains, such as the first macrodomain of mono-ADP-ribosyltransferase PARP14 (PARP-14, also known as ADP-ribosyltransferase diphtheria toxin-like 8, ATRD8, B aggressive lymphoma protein 2, or BAL2). Most BAL proteins also contain a C-terminal PARP active site and are also named as PARPs. Human BAL1 (or PARP-9) was originally identified as a risk-related gene in diffuse large B-cell lymphoma that promotes malignant B-cell migration. Some BAL family proteins exhibit PARP activity. Poly (ADP-ribosyl)ation is an immediate DNA-damage-dependent post-translational modification of histones and other nuclear proteins. BAL proteins may also function as transcriptional repressors.

X-domain (or Mac1 domain) of viral non-structural protein 3 and related macrodomains; The X-domain, also called Mac1, is the macrodomain found in riboviral non-structural protein 3 (Nsp3), including the Nsp3 of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) as well as SARS-CoV-2, and other coronaviruses (alpha-, beta-, gamma-, and deltacoronavirus), among others. The SARS-CoV-2 Nsp3 Mac1 is highly conserved among all CoVs, and binds to and hydrolyzes mono-ADP-ribose (MAR) from target proteins. It appears to counter host-mediated antiviral ADP-ribosylation, a post-translational modification that is part of the host response to viral infections. Mac1 is essential for pathogenesis in multiple animal models of CoV infection, implicating it as a virulence factor and potential therapeutic target. Assays show that the de-MARylating activity leads to a rapid loss of substrate, and that Mac1 could not hydrolyze poly-ADP-ribose; thus, Mac1 is a MAR-hydrolase (mono-ADP ribosylhydrolase). Mac1 was originally named ADP-ribose-1"-phosphatase (ADRP) based on data demonstrating that it could remove the phosphate group from ADP-ribose-1"-phosphate; however, activity was modest and was unclear why this would impact a virus infection. This family also includes the X-domain of Avian infectious bronchitis virus (IBV) strain Beaudette coronavirus that does not bind ADP-ribose; the triple glycine sequence found in the X-domains of SARS-CoV and human coronavirus 229E (HCoV229E), which are involved in ADP-ribose binding, is not conserved in the IBV X-domain. SARS-CoVs have two other macrodomains referred to as the SUD-N (N-terminal subdomain, or Mac2) and SUD-M (middle SUD subdomain, or Mac3) of the SARS-unique domain (SUD), which also do not bind ADP-ribose; these bind G-quadruplexes (unusual nucleic-acid structures formed by consecutive guanosine nucleotides). SARS-CoV SUD-N and SUD-M are not included in this group.

Macrodomain, uncharacterized family similar to Thermus thermophilus hypothetical protein Ttha0132; Macrodomains are found in a variety of proteins with diverse cellular functions, as a stand-alone domain or in combination with other domains like in histone macroH2A and some PARPs (poly ADP-ribose polymerases). Macrodomains can recognize ADP-ribose (ADPr) in both its free and protein-linked forms, in related ligands, such as O-acyl-ADP-ribose (OAADPr), and even in ligands unrelated to ADPr. Macrodomains include the yeast macrodomain Poa1 which is a phosphatase of ADP-ribose-1"-phosphate, a by-product of tRNA splicing. Some macrodomains have ADPr-unrelated binding partners such as the coronavirus SUD-N (N-terminal subdomain) and SUD-M (middle subdomain) of the SARS-unique domain (SUD) which bind G-quadruplexes (unusual nucleic-acid structures formed by consecutive guanosine nucleotides). Macrodomains regulate a wide variety of cellular and organismal processes, including DNA damage repair, signal transduction, and immune response. This family is composed of uncharacterized proteins containing a stand-alone macrodomain, similar to Thermus thermophilus hypothetical protein Ttha0132.
