Target Background

Function

Together with PML, this tumor suppressor is a major constituent of the PML bodies, a subnuclear organelle involved in a large number of physiological processes including cell growth, differentiation and apoptosis. Functions as a transcriptional coactivator of ETS1 and ETS2 according to PubMed:11909962. Under certain conditions, it may also act as a corepressor of ETS1 preventing its binding to DNA according to PubMed:15247905. Through the regulation of ETS1 it may play a role in angiogenesis, controlling endothelial cell motility and invasion. Through interaction with the MRN complex it may be involved in the regulation of telomeres lengthening. May also regulate TP53-mediated transcription and through CASP8AP2, regulate FAS-mediated apoptosis. Also plays a role in infection by viruses, including human cytomegalovirus and Epstein-Barr virus, through mechanisms that may involve chromatin and/or transcriptional regulation.

Gene References into Functions

the ND10 bodies become viral replication compartments, and ICP0, a viral E3 ligase, degrades both PML and SP100. The amounts of PML and SP100 and the number of ND10 structures increase in cells exposed to IFN-beta. PMID: 28439026

Data suggest that nuclear antigen Sp100C is a multifaceted histone H3 methylation and phosphorylation sensor. PMID: 27129259
These results suggest that high-risk human papillomavirus 31 target interferon kappa to prevent Sp100 expression and identify Sp100 as an interferon-stimulated gene with anti-human papillomavirus activity. PMID: 26491169
PML, hDaxx and Sp100 primarily act as cellular restriction factors during lytic human cytomegalovirus replication and during the dynamic process of reactivation but do not serve as key determinants for the establishment of latency. PMID: 26057166
Sp100 repressed viral transcription and replication only during the initial stages of viral establishment, suggesting that Sp100 acts as a repressor of incoming human papillomavirus type 18 DNA. PMID: 24194542
Sp100 depletion promotes Adenovirus progeny production and early viral protein synthesis. PMID: 24623443
Two regions within the N-terminal of the herpes simplex virus 1 ICP0 facilitate the degradation and dissociation of host PML and dissociation of Sp100 from ND10. PMID: 24089549
Sp100 is recruited to activated arrays in cells expressing the herpes simplex virus type 1 E3 ubiquitin ligase, ICP0, which degrades all Sp100 isoforms except unsumoylated Sp100A. PMID: 23485562
The results suggest that hantavirus infection interferes with DAXX-mediated apoptosis, and expression of interferon-activated Sp100 and ISG-20 proteins may indicate intracellular intrinsic antiviral attempts. PMID: 23830076
SP100 and Adeno-associated virus 2 Rep78 are both located in the nucleolus, which provides the spatial possibility for their interaction. PMID: 22419217
Authors conclude that several ND10 components, including Daxx, the promyelocytic leukemia (PML) protein, and Sp100 cooperate in an additive manner to regulate herpes simplex virus type 1 and human cytomegalovirus infection. PMID: 23221561
Herpesvirus saimiri tegument protein specifically degraded the cellular ND10 component Sp100. PMID: 22278248
These findings expand our knowledge of both Sp100 and Cdc20 as well as their role in ubiquitination. PMID: 22086178
These findings indicate that thehuman herpesvirus 5 IE1-dependent loss of human Sp100 proteins during virus infection may represent an important requirement for efficient viral growth. PMID: 21880768
Taken together, these data provide evidence that Sp100 is the first ND10-related factor identified that not only possesses the potential to restrict the initial stage of infection but also inhibits cytomegalovirus replication during the late phase. PMID: 21734036
Sp100 counteract human cytomegalovirus infection via the repression of viral immediate-early gene expression. PMID: 21471311

SP100 modulates ETS1-dependent biological processes PMID: 15247905
Genes that are negatively regulated by ETS1 and upregulated by SP100 have antimigratory or antiangiogenic properties. PMID: 15592518
EBNA-LP interacts with the promyelocytic leukemia nuclear body (PML NB)-associated protein Sp100 and displaces Sp100 and heterochromatin protein 1alpha (HP1alpha) from PML NBs. PMID: 16177824
Repressive Sp100 isoforms B, C, and HMG are an essential part of the IFN-beta-mediated suppression of ICP0 expression. PMID: 16873258
Sp100 isoforms suppress immediate-early HSV-1 proteins at the promoter level and that IFN changes the splicing pattern of the Sp100 transcript to the suppressing Sp100C isoform. PMID: 19279115

Subcellular Location

Nucleus. Nucleus, PML body. Cytoplasm. Note=Differences in the subnuclear localization of the different isoforms seem to exist and may also be cell cycle- and interferon-dependent. Accumulates in the cytoplasm upon FAS activation.; [Isoform Sp100-C]: Nucleus. Note=Forms a reticulate or track-like nuclear pattern with denser concentrations at the nuclear lamina and surrounding the nucleoli, a pattern reminiscent of heterochromatin-rich regions according to PubMed:11313457.

Tissue Specificity

Widely expressed. Sp100-B is expressed only in spleen, tonsil, thymus, mature B-cell line and some T-cell line, but not in brain, liver, muscle or non-lymphoid cell lines.
