| Function |
Functions as an E3-type small ubiquitin-like modifier (SUMO) ligase, stabilizing the interaction between UBE2I and the substrate, and as a SUMO-tethering factor. Plays a crucial role as a transcriptional coregulation in various cellular pathways, including the STAT pathway and the steroid hormone signaling pathway. Involved in regulating STAT3 signaling via inhibiting STAT3 DNA-binding and suppressing cell growth. Enhances the sumoylation of MTA1 and may participate in its paralog-selective sumoylation. {ECO:0000269|PubMed:21965678, ECO:0000269|PubMed:9388184}.
|
| Subcellular Location |
Cytoplasm. Nucleus. Note=Mainly cytoplasmic but shuttles between the nucleus and cytoplasm. Transported to the nucleus on interaction with phosphorylated STAT3. Colocalizes with GFI1 in nuclear dots (By similarity). {ECO:0000250}.
|
| Tissue Specificity |
Isoform 1 is expressed in most tissues except thymus and small intestine. Isoform 3 is expressed only in brain, heart, thymus, muscle, lung, testis, lactating breast and embryonic stem cells. {ECO:0000269|PubMed:9388184}.
