[[http://www.uniprot.org/uniprot/SUMO1_HUMAN SUMO1_HUMAN]] Defects in SUMO1 are the cause of non-syndromic orofacial cleft type 10 (OFC10) [MIM:[http://omim.org/entry/613705 613705]]; also called non-syndromic cleft lip with or without cleft palate 10. OFC10 is a birth defect consisting of cleft lips with or without cleft palate. Cleft lips are associated with cleft palate in two-third of cases. A cleft lip can occur on one or both sides and range in severity from a simple notch in the upper lip to a complete opening in the lip extending into the floor of the nostril and involving the upper gum. Note=A chromosomal aberation involving SUMO1 is the cause of OFC10. Translocation t(2;8)(q33.1;q24.3). The breakpoint occurred in the SUMO1 gene and resulted in haploinsufficiency confirmed by protein assays.<ref>PMID:16990542</ref> [[http://www.uniprot.org/uniprot/PML_HUMAN PML_HUMAN]] Note=A chromosomal aberration involving PML may be a cause of acute promyelocytic leukemia (APL). Translocation t(15;17)(q21;q21) with RARA. The PML breakpoints (type A and type B) lie on either side of an alternatively spliced exon.<ref>PMID:1652369</ref> <ref>PMID:1720570</ref>

[[http://www.uniprot.org/uniprot/SUMO1_HUMAN SUMO1_HUMAN]] Ubiquitin-like protein that can be covalently attached to proteins as a monomer or a lysine-linked polymer. Covalent attachment via an isopeptide bond to its substrates requires prior activation by the E1 complex SAE1-SAE2 and linkage to the E2 enzyme UBE2I, and can be promoted by E3 ligases such as PIAS1-4, RANBP2 or CBX4. This post-translational modification on lysine residues of proteins plays a crucial role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduction. Involved for instance in targeting RANGAP1 to the nuclear pore complex protein RANBP2. Polymeric SUMO1 chains are also susceptible to polyubiquitination which functions as a signal for proteasomal degradation of modified proteins. May also regulate a network of genes involved in palate development.<ref>PMID:9019411</ref> <ref>PMID:9162015</ref> <ref>PMID:18538659</ref> <ref>PMID:18408734</ref> [[http://www.uniprot.org/uniprot/PML_HUMAN PML_HUMAN]] Key component of PML nuclear bodies that regulate a large number of cellular processes by facilitating post-translational modification of target proteins, promoting protein-protein contacts, or by sequestering proteins. Functions as tumor suppressor. Required for normal, caspase-dependent apoptosis in response to DNA damage, FAS, TNF, or interferons. Plays a role in transcription regulation, DNA damage response, DNA repair and chromatin organization. Plays a role in processes regulated by retinoic acid, regulation of cell division, terminal differentiation of myeloid precursor cells and differentiation of neural progenitor cells. Required for normal immunity to microbial infections. Plays a role in antiviral response. In the cytoplasm, plays a role in TGFB1-dependent processes. Regulates p53/TP53 levels by inhibiting its ubiquitination and proteasomal degradation. Regulates activation of p53/TP53 via phosphorylation at 'Ser-20'. Sequesters MDM2 in the nucleolus after DNA damage, and thereby inhibits ubiquitination and degradation of p53/TP53. Regulates translation of HIF1A by sequestering MTOR, and thereby plays a role in neoangiogenesis and tumor vascularization. Regulates RB1 phosphorylation and activity. Required for normal development of the brain cortex during embryogenesis. Can sequester herpes virus and varicella virus proteins inside PML bodies, and thereby inhibit the formation of infectious viral particles. Regulates phosphorylation of ITPR3 and plays a role in the regulation of calcium homeostasis at the endoplasmic reticulum (By similarity). Regulates transcription activity of ELF4. Inhibits specifically the activity of the tetrameric form of PKM. Together with SATB1, involved in local chromatin-loop remodeling and gene expression regulation at the MHC-I locus. Regulates PTEN compartmentalization through the inhibition of USP7-mediated deubiquitination.<ref>PMID:9756909</ref> <ref>PMID:10610177</ref> <ref>PMID:10684855</ref> <ref>PMID:11025664</ref> <ref>PMID:11432836</ref> <ref>PMID:12402044</ref> <ref>PMID:12439746</ref> <ref>PMID:12810724</ref> <ref>PMID:14976184</ref> <ref>PMID:15195100</ref> <ref>PMID:15356634</ref> <ref>PMID:17030982</ref> <ref>PMID:18298799</ref> <ref>PMID:18716620</ref> <ref>PMID:17173041</ref> <ref>PMID:19567472</ref> <ref>PMID:21172801</ref> <ref>PMID:21304940</ref>
