== Function ==
[https://www.uniprot.org/uniprot/SP100_HUMAN SP100_HUMAN] 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.<ref>PMID:11909962</ref> <ref>PMID:14647468</ref> <ref>PMID:15247905</ref> <ref>PMID:15592518</ref> <ref>PMID:15767676</ref> <ref>PMID:16177824</ref> <ref>PMID:17245429</ref> <ref>PMID:21274506</ref> <ref>PMID:21880768</ref>

== Publication Abstract from PubMed ==
The SAND domain is a conserved sequence motif found in a number of nuclear proteins, including the Sp100 family and NUDR. These are thought to play important roles in chromatin-dependent transcriptional regulation and are linked to many diseases. We have determined the three-dimensional (3D) structure of the SAND domain from Sp100b. The structure represents a novel alpha/beta fold, in which a conserved KDWK sequence motif is found within an alpha-helical, positively charged surface patch. For NUDR, the SAND domain is shown to be sufficient to mediate DNA binding. Using mutational analyses and chemical shift perturbation experiments, the DNA binding surface is mapped to the alpha-helical region encompassing the KDWK motif. The DNA binding activity of wild type and mutant proteins in vitro correlates with transcriptional regulation activity of full length NUDR in vivo. The evolutionarily conserved SAND domain defines a new DNA binding fold that is involved in chromatin-associated transcriptional regulation.
The SAND domain structure defines a novel DNA-binding fold in transcriptional regulation.,Bottomley MJ, Collard MW, Huggenvik JI, Liu Z, Gibson TJ, Sattler M Nat Struct Biol. 2001 Jul;8(7):626-33. PMID:11427895<ref>PMID:11427895</ref>
