General description

Small ubiquitin-related modifier 1 (UniProt: P63165; also known as SUMO-1, GAP-modifying protein 1, GMP1, SMT3 homolog 3, Sentrin, Ubiquitin-homology domain protein PIC1, Ubiquitin-like protein SMT3C, Smt3C, Ubiquitin-like protein UBL1) is encoded by the SUMO1 (also known as SMT3C, SMT3H3, UBL1, OK/SW-cl.43) gene (Gene ID: 7341) in human. SUMO-1 is a ubiquitin-like protein that can be covalently attached to proteins as a monomer or 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 E3 ligases such as PIAS1-4, RANBP2 or CBX4. This post-translational modification on lysine residues of proteins plays a crucial role in many cellular processes, such as nuclear transport, DNA replication and repair, mitosis and signal transduction. SUMO-1 can also covalently attach to the voltage-gated potassium channel KCNB1; this modulates the gating characteristics of KCNB1. Polymeric SUMO-1 chains are shown to be susceptible to polyubiquitination, which functions as a signal for proteasomal degradation of modified proteins. Two isoforms of SUMO-1 have been reported that are produced by alternative splicing. Mutations in SUMO1 gene are known to cause non-syndromic orofacial cleft 10, which is a birth defect consisting of cleft lips with or without cleft palate.
