	homolog to SUMO2 (97p100)

Homologene

FAMILY	ubiquitin family

CATEGORY

regulatory

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm
	intracellular,nucleus,chromatin/chromosome,centromere
	intracellular,nucleus,chromatin/chromosome,kinetochore
text	SUMO-2/3 localize to centromeres and condensed chromosomes
	ARHGAP21 co-localizes with SUMO2/3 in the cytoplasm and membrane compartments

basic FUNCTION	involved in the function and/or structure of the eukaryotic kinetochore
	ubiquitin-like protein that can be conjugated to other proteins in a manner analogous to ubiquitination
	SUMO-2/3 conjugation and the ubiquitin-proteasome system are tightly integrated and act in a cooperative manner
	with other SUMO proteins, binding to lysine residues of target proteins and thereby modifying their stability, activity and subcellular localization
	with SUMO2 and SUMO1 accumulate at DNA double-strand breaks sites in mammalian cells, with SUMO1 and SUMO2/3 accrual requiring the E3 ligase enzymes PIAS4 and PIAS1
	SUMO2 and SUMO3 can rapidly convert to be conjugated in response to a variety of cellular stresses

CELLULAR PROCESS

protein, degradation

PHYSIOLOGICAL PROCESS

cellular trafficking transport

PATHWAY

metabolism

signaling

a component

kinetochore

INTERACTION

DNA

RNA

small molecule

protein	targeting proteins
	covalently binding and modifying RANGAP1 involved in nuclear transport
	interacting with CENPE (CENPE was found to be modified specifically by SUMO-2/3 and to possess SUMO-2/3 polymeric chain-binding activity essential for kinetochore localization)

REGULATION

repressed by

expression of SUMO3, can be down-regulated at the transcription level by cellular oxidative stress
