Summary
SUMO2 (small ubiquitin like modifier 2, HGNC:11125) is a protein-coding gene on chromosome 17q25, encoding Small ubiquitin-related modifier 2 (P61956). Ubiquitin-like protein that can be covalently attached to proteins as a monomer or as a lysine-linked polymer. It is a selective cancer dependency (DepMap: 80.8% of cell lines).
This gene encodes a protein that is a member of the SUMO (small ubiquitin-like modifier) protein family. It functions in a manner similar to ubiquitin in that it is bound to target proteins as part of a post-translational modification system. However, unlike ubiquitin which targets proteins for degradation, this protein is involved in a variety of cellular processes, such as nuclear transport, transcriptional regulation, apoptosis, and protein stability. It is not active until the last two amino acids of the carboxy-terminus have been cleaved off. Numerous pseudogenes have been reported for this gene. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.

UniProt curated annotations — full annotation on UniProt →
Function. Ubiquitin-like protein that can be covalently attached to proteins as a monomer or as a lysine-linked polymer. Covalent attachment via an isopeptide bond to its substrates requires prior activation by the E1 complex SAE1-SAE2 and linkage to the E2 enzyme UBE2I, and can be promoted by an E3 ligase such as PIAS1-4, RANBP2, CBX4 or ZNF451. This post-translational modification on lysine residues of proteins plays a crucial role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduction. Polymeric SUMO2 chains are also susceptible to polyubiquitination which functions as a signal for proteasomal degradation of modified proteins. Plays a role in the regulation of sumoylation status of SETX.
Subunit / interactions. Interacts with SAE2 and UBE2I. Interacts with ZNF451. Identified in a complex with ZNF451 and UBE2I/UBC9, where one ZNF451 interacts with one UBE2I/UBC9 and two SUMO2 chains, one bound to the UBE2I/UBC9 active site and the other to another region of the same UBE2I/UBC9 molecule. Covalently attached to a number of proteins. Interacts with PELP1. Interacts with USP25; the interaction sumoylates USP25. Interacts with SIMC1, CASP8AP2, RNF111 and SOBP (via SIM domains). Interacts with MTA1. Interacts with HINT1. Interacts with GCNA (via SIM domains); this interaction allows the GCNA recruitment to DPCs sites. Interacts with TINCR (via SUMO-interacting motif); the interaction increases TINCR protein stability. (Microbial infection) Interacts with Epstein-barr virus BGLF4.
Subcellular location. Nucleus. PML body.
Tissue specificity. Broadly expressed.
Post-translational modifications. Polymeric chains can be formed through Lys-11 cross-linking. Polymeric SUMO2 chains undergo ‘Lys-6’-, ‘Lys-11’-, ‘Lys-48’- and ‘Lys-63’-linked polyubiquitination by RNF4. Cleavage of precursor form by SENP1 or SENP2 is necessary for function. Monoubiquitinated N-terminally by UBE2W, which primes it for RNF4-dependent polyubiquitination by the UBE2V1-UBE2N heterodimer.
Similarity. Belongs to the ubiquitin family. SUMO subfamily.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 58 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
