SUMO

Ubiquitin-like protein which can be covalently attached to target lysines as a monomer. Does not seem to be involved in protein degradation and may function as an antagonist of ubiquitin in the degradation process. Plays a role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduction. Covalent attachment to its substrates requires prior activation by the E1 complex aos-1-uba-2 and linkage to the E2 enzyme ubc-9, and can be promoted by an E3 ligase such as gei-17. Required for embryonic development, fertility, vulval morphogenesis and inhibition of vulval cell fates. Probably by sumoylating bet-1, prevents muscle myosin depletion in aging adults probably by preventing myoblast growth factor receptor egl-15 overexpression. Plays a role in the attenuation of the let-60/ras pathway.

At the first embryonic mitotic division, enriched in the nucleus and released to the cytoplasm when the nuclear envelope breaks down at the start of mitosis. During mitosis, localizes to the metaphase plate and to the centrosomal region. Also localizes to segregating chromosomes at the beginning of anaphase. At late anaphase and telophase, observed in the spindle midzone and in the two daughter nuclei.

Cleavage of precursor form by ulp-1 is necessary for function.
