SUMOylation (Homo sapiens)
From WikiPathways
Description
Small Ubiquitin-like MOdifiers (SUMOs) are a family of 3 proteins (SUMO1,2,3) that are reversibly conjugated to lysine residues of target proteins via a glycine-lysine isopeptide bond (reviewed in Hay 2013, Hannoun et al. 2010, Gareau and Lima 2010, Wilkinson and Henley 2010, Wang and Dasso 2009). Proteomic methods have yielded estimates of hundreds of target proteins. Targets are mostly located in the nucleus and therefore SUMOylation disproportionately affects gene expression.
SUMOs are initially translated as proproteins possessing extra amino acid residues at the C-terminus which are removed by the SUMO processing endoproteases SENP1,2,5 (Hay 2007). Different SENPs have significantly different efficiencies with different SUMOs. The processing exposes a glycine residue at the C-terminus that is activated by ATP-dependent thiolation at cysteine-173 of UBA2 in a complex with SAE1, the E1 complex. The SUMO is transferred from E1 to cysteine-93 of a single E2 enzyme, UBC9 (UBE2I). UBC9 with or, in some cases, without an E3 ligase conjugates the glycine C-terminus of SUMO to an epsilon amino group of a lysine residue on the target protein. SUMO2 and SUMO3 may then be further polymerized, forming chains. SUMO1 is unable to form polymers.
Conjugated SUMO can act as a biinding site for proteins possessing SUMO interaction motifs (SIMs) and can also directly affect the formation of complexes between the target protein and other proteins.
Conjugated SUMOs are removed by cleavage of the isopeptide bond by processing enzymes SENP1,2,3,5. The processing enzymes SENP6 and SENP7 edit chains of SUMO2 and SUMO3. View original pathway at:Reactome.

SUMO E3 ligases
SUMOylate target proteins | Pathway | R-HSA-3108232 (Reactome) | SUMO proteins are conjugated to lysine residues of target proteins via an isopeptide bond with the C-terminal glycine of SUMO (reviewed in Zhao 2007, Gareau and Lima 2010, Hannoun et al. 2010, Citro and Chiocca 2013, Yang and Chiang 2013). Proteomic analyses indicate that SUMO is conjugated to hundreds of proteins and most targets of SUMOylation are nuclear (Vertegal et al. 2006, Bruderer et al. 2011, Tatham et al. 2011, Da Silva et al. 2012, Becker et al. 2013). UBE2I (UBC9), the E2 activating enzyme of the SUMO pathway, is itself also a SUMO E3 ligase. Most SUMOylation reactions will proceed with only the substrate protein and the UBE2I:SUMO thioester conjugate. The rates of some reactions are further enhanced by the action of other E3 ligases such as RANBP2. These E3 ligases catalyze SUMO transfer to substrate by one of two basic mechanisms: they interact with both the substrate and UBE2I:SUMO thus bringing them into proximity or they enhance the release of SUMO from UBE2I to the substrate. Most SUMOylation reactions occur in the nucleoplasm therefore most targets of SUMOylation are nuclear proteins such as transcription factors, transcription cofactors, and nuclear receptors. In the cell SUMO1 is mainly concentrated at the nuclear membrane and in nuclear bodies. Most SUMO1 is conjugated to RANGAP1 near the nuclear pore. SUMO2 is at least partially cytosolic and SUMO3 is located mainly in nuclear bodies. Most SUMO2 and SUMO3 is unconjugated in unstressed cells and becomes conjugated to target proteins in response to stress (Golebiowski et al. 2009). Especially notable is the requirement for recruitment of SUMO to sites of DNA damage where conjugation to targets seems to coordinate the repair process (Flotho and Melchior 2013). Several effects of SUMOylation have been described: steric interference with protein-protein interactions, interference with other post-translational modifications such as ubiquitinylation and phosphorylation, and recruitment of proteins that possess a SUMO-interacting motif (SIM) (reviewed in Zhao 2007, Flotho and Melchior 2013, Jentsch and Psakhye 2013, Yang and Chiang 2013). In most cases SUMOylation inhibits the activity of the target protein. The SUMOylation reactions included in this module have met two criteria: They have been verified by assays of individual proteins (as opposed to mass proteomic assays) and the effect of SUMOylation on the function of the target protein has been tested. |

R-HSA-2990833 (Reactome) | The UBA2:SAE1 complex catalyzes the formation of a thioester bond between SUMO1 and cysteine-173 of UBA2 (Desterro et al. 1999, Okuma et al. 1999, Werner et al. 2009, Olsen et al. 2010, Wang and Chen 2010). ATP reacts with the C-terminal glycine residue of SUMO1 to yield pyrophosphate and a transient intermediate, SUMO1 adenylate, which then reacts with the thiol group of the cysteine residue on UBA2. | |||
R-HSA-2990840 (Reactome) | The SUMO1 precursor has 4 extra residues at the C-terminus which can be removed endoproteolytically by either SENP1, SENP2, or SENP5 (Zheng and Au, 2005, Mikolajczyk et al. 2007). The order of processing activity is: SENP1 greater than SENP2 greater than SENP5 (Mikolajczyk et al. 2007). Both SENP1 and SENP2 shuttle between the nucleus and cytoplasmic and both are predominantly nucleoplasmic (Bailey and O'Hare 2004, Kim et al. 2005, Zhang et al. 2002, Hang and Dasso 2002, Itahana et al. 2006). | |||
R-HSA-2990842 (Reactome) | The SUMO2 precursor has 2 extra residues at the C-terminus which can be removed endoproteolytically by SENP1, SENP2, or SENP5 (Zheng and Au, 2005, Gong and Yeh 2006, Mikolajczyk et al. 2007). The order of processing activity is: SENP1 greater than SENP2 greater than SENP5 (Mikolajczyk et al. 2007). SENP2 and SENP5 have highest activity on SUMO2, however the processing activity of SENP1 is higher overall (Mikolajczyk et al. 2007). SENP1 and SENP2 shuttle between the nucleus and cytosol and are predominantly nuclear (Bailey and O'Hare 2004, Kim et al. 2005, Zhang et al. 2002, Hang and Dasso 2002, Itahana et al. 2006). SENP5 is located in the nucleolus (Di Bacco et al. 2006, Gong and Yeh 2006). | |||
R-HSA-2993763 (Reactome) | The SUMO3 precursor has 11 extra residues at the C-terminus which can be removed endoproteolytically by SENP1, SENP2, or SENP5 (Zheng and Au, 2005, Gong and Yeh 2006, Mikolajczyk et al. 2007). The order of processing activity is: SENP1 greater than SENP2 greater than SENP5 (Mikolajczyk et al. 2007). Overall, processing of SUMO3 is the lowest of any SUMO (Mikolajczyk et al. 2007). SENP1 and SENP2 shuttle between the nucleus and cytosol and are predominantly nuclear (Bailey and O'Hare 2004, Kim et al. 2005, Zhang et al. 2002, Hang and Dasso 2002, Itahana et al. 2006). SENP5 is located in the nucleolus (Di Bacco et al. 2006, Gong and Yeh 2006). | |||
R-HSA-2993769 (Reactome) | SUMO3 is transferred from cysteine-173 of UBA2 to cysteine-93 of UBC9 (UBE2I) in a transthiolation reaction (Tatham et al. 2001, Werner et al. 2009). | |||
R-HSA-2993780 (Reactome) | SUMO1 is transferred from cysteine-173 of UBA2 to cysteine-93 of UBC9 (UBE2I) in a transthiolation reaction (Desterro et al. 1999, Okuma et al. 1999, Tatham et al. 2003, Lois and Lima 2005, Wang et al. 2007, Werner et al. 2009). The UbL domain of E1 recruits E2 into proximity for the transfer of SUMO (Lois and Lima 2005, Wang et al. 2009), | |||
R-HSA-2993781 (Reactome) | The UBA2:SAE1 complex catalyzes the formation of a thioester bond between SUMO3 and cysteine-173 of UBA2 (Tatham et al. 2001, Werner et al. 2009). ATP reacts with the C-terminal glycine residue of SUMO3 to yield pyrophosphate and a transient intermediate, SUMO3 adenylate, which then reacts with the thiol group of the cysteine residue on UBA2. | |||
R-HSA-2993784 (Reactome) | The UBA2:SAE1 complex catalyzes the formation of a thioester bond between SUMO2 and cysteine-173 of UBA2 (Tatham et al. 2001, Werner et al. 2009). ATP reacts with the C-terminal glycine residue of SUMO2 to yield pyrophosphate and a transient intermediate, SUMO2 adenylate, which then reacts with the thiol group of the cysteine residue on UBA2. | |||
R-HSA-2993790 (Reactome) | SUMO2 is transferred from cysteine-173 of UBA2 to cysteine-93 of UBC9 (UBE2I) in a transthiolation reaction (Tatham et al. 2001, Werner et al. 2009). | |||
