== Function == | |||
[https://www.uniprot.org/uniprot/SUMO2_HUMAN SUMO2_HUMAN] 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 or CBX4. 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.<ref>PMID:9556629</ref> <ref>PMID:18538659</ref> <ref>PMID:18408734</ref> | |||

== Publication Abstract from PubMed == | |||
RNF4 [RING (really interesting new gene) finger protein 4] is a SUMO-targeted ubiquitin ligase (STUbL) controlling promyelocytic leukemia (PML) nuclear bodies, DNA double strand break repair and other nuclear functions. We describe that the sequence and spacing of the SUMO-interaction motifs (SIMs) in RNF4 regulate the avidity-driven recognition of substrate proteins carrying SUMO chains of variable length. | |||
Multivalent interactions of the SUMO-interaction motifs in the RING-finger protein 4 (RNF4) determine the specificity for chains of the small ubiquitin-related modifier (SUMO).,Keusekotten K, Bade VN, Meyer-Teschendorf K, Sriramachandran AM, Fischer-Schrader K, Krause A, Horst C, Schwarz G, Hofmann K, Dohmen RJ, Praefcke GJ Biochem J. 2013 Oct 23.
