Protein mono-ADP-ribosyltransferase PARP16; Intracellular mono-ADP-ribosyltransferase that may play a role in different processes through the mono-ADP-ribosylation of proteins involved in those processes. May play a role in the unfolded protein response (UPR), by ADP-ribosylating and activating EIF2AK3 and ERN1, two important UPR effectors. May also mediate mono-ADP- ribosylation of karyopherin KPNB1 a nuclear import factor. May not modify proteins on arginine or cysteine residues compared to other mono-ADP-ribosyltransferases.

Protein mono-ADP-ribosyltransferase PARP4; Mono-ADP-ribosyltransferase that mediates mono-ADP- ribosylation of target proteins.

Protein mono-ADP-ribosyltransferase PARP8; Mono-ADP-ribosyltransferase that mediates mono-ADP- ribosylation of target proteins.

Protein mono-ADP-ribosyltransferase PARP6; Mono-ADP-ribosyltransferase that mediates mono-ADP- ribosylation of target proteins.

Protein mono-ADP-ribosyltransferase PARP3; Mono-ADP-ribosyltransferase that mediates mono-ADP- ribosylation of target proteins and plays a key role in the response to DNA damage. Mediates mono-ADP- ribosylation of glutamate, aspartate or lysine residues on target proteins (By similarity). In contrast to PARP1 and PARP2, it is not able to mediate poly-ADP-ribosylation (By similarity). Associates with a number of DNA repair factors and is involved in the response to exogenous and endogenous DNA strand breaks. Together with APLF, promotes the retention of the LIG4-XRCC4 complex on chromat [...]

tRNA 2'-phosphotransferase 1; Catalyzes the last step of tRNA splicing, the transfer of the splice junction 2'-phosphate from ligated tRNA to NAD to produce ADP- ribose 1''-2'' cyclic phosphate; Belongs to the KptA/TPT1 family.

Poly [ADP-ribose] polymerase 2; Poly-ADP-ribosyltransferase that mediates poly-ADP- ribosylation of proteins and plays a key role in DNA repair. Mainly mediates glutamate and aspartate ADP- ribosylation of target proteins: the ADP-D-ribosyl group of NAD(+) is transferred to the acceptor carboxyl group of glutamate and aspartate residues and further ADP-ribosyl groups are transferred to the 2'- position of the terminal adenosine moiety, building up a polymer with an average chain length of 20-30 units (By similarity). ADP- ribosylation follows DNA damage and appears as an obligatory ste [...]

E3 ubiquitin-protein ligase RNF114; E3 ubiquitin-protein ligase that promotes the ubiquitination of various substrates. In turn, participates in the regulation of many biological processes including cell cycle, apoptosis, osteoclastogenesis as well as innate or adaptive immunity. Acts as negative regulator of NF-kappa-B-dependent transcription by promoting the ubiquitination and stabilization of the NF-kappa-B inhibitor TNFAIP3. May promote the ubiquitination of TRAF6 as well. Acts also as a negative regulator of T-cell activation. Inhibits cellular dsRNA responses and interferon produ [...]

ADP-ribose glycohydrolase ARH3; ADP-ribose glycohydrolase that preferentially hydrolyzes the scissile alpha-O-linkage attached to the anomeric C1'' position of ADP- ribose and acts on different substrates, such as proteins ADP- ribosylated on serine, free poly(ADP-ribose) and O-acetyl-ADP-D-ribose (By similarity). Specifically acts as a serine mono-ADP- ribosylhydrolase by mediating the removal of mono-ADP-ribose attached to serine residues on proteins, thereby playing a key role in DNA damage response (By similarity). Serine ADP-ribosylation of proteins constitutes the primary form of [...]
