ID:UBC9_HUMAN DESCRIPTION: RecName: Full=SUMO-conjugating enzyme UBC9; EC=6.3.2.-; AltName: Full=SUMO-protein ligase; AltName: Full=Ubiquitin carrier protein 9; AltName: Full=Ubiquitin carrier protein I; AltName: Full=Ubiquitin-conjugating enzyme E2 I; AltName: Full=Ubiquitin-protein ligase I; AltName: Full=p18; FUNCTION: Accepts the ubiquitin-like proteins SUMO1, SUMO2, SUMO3 and SUMO4 from the UBLE1A-UBLE1B E1 complex and catalyzes their covalent attachment to other proteins with the help of an E3 ligase such as RANBP2 or CBX4. Can catalyze the formation of poly- SUMO chains. Necessary for sumoylation of FOXL2 and KAT5. Essential for nuclear architecture and chromosome segregation. CATALYTIC ACTIVITY: ATP + SUMO + protein lysine = AMP + diphosphate + protein N-SUMOyllysine. PATHWAY: Protein modification; protein sumoylation. SUBUNIT: Interacts with HIPK1, HIPK2, PPM1J, RASD2 and TCF3 Interacts with NR2C1; the interaction promotes its sumoylation (By similarity). Forms a tight complex with RANGAP1 and RANBP2. Interacts with SIAH1 and PARP. Interacts with various transcription factors such as TFAP2A, TFAP2B, TFAP2C, AR, ETS1 and SOX4. Interacts with RWDD3; the interaction enhances the sumoylation of a number of proteins such as HIF1A and I-kappa-B. Interacts with DNMT1. Interacts with FOXL2. Forms a complex with SENP6 and UBE2I in response to UV irradiation. Interacts with human herpesvirus 6 IE2. Interacts with human adenovirus early E1A protein; this interaction interferes with polysumoylation (Probable). Interacts with DNM1l (via its GTPase and B domains); the interaction promotes sumoylation of DNM1L, mainly in its B domain. Interacts with PML-RARA oncoprotein (via the coiled-colied domain); the interaction is required for sumoylation of the PML- RARA oncoprotein. Interacts with IPO13. Interacts with NFATC2IP; this inhibits formation of poly-SUMO chains.

Cytoplasm. Note=Mainly nuclear. In spermatocytes, localizes in synaptonemal complexes. Recruited by BCL11A into the nuclear body (By similarity). TISSUE SPECIFICITY: Expressed in heart, skeletal muscle, pancreas, kidney, liver, lung, placenta and brain. Also expressed in testis and thymus. SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family. SEQUENCE CAUTION: Sequence=AAH51289.3; Type=Erroneous initiation; Note=Translation N-terminally shortened; Sequence=BAD92225.1; Type=Erroneous initiation; Note=Translation N-terminally shortened;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
