CC -!- FUNCTION: NAD-dependent protein-lysine deacylase that can act both as a
CC deacetylase or deacylase (desuccinylase, depropionylase and
CC deglutarylase), depending on the context. Specifically mediates
CC deacetylation of histone H3 at 'Lys-18' (H3K18Ac). In contrast to other
CC histone deacetylases, displays strong preference for a specific histone
CC mark, H3K18Ac, directly linked to control of gene expression. H3K18Ac
CC is mainly present around the transcription start site of genes and has
CC been linked to activation of nuclear hormone receptors; SIRT7 thereby
CC acts as a transcription repressor. Moreover, H3K18 hypoacetylation has
CC been reported as a marker of malignancy in various cancers and seems to
CC maintain the transformed phenotype of cancer cells. Also able to
CC mediate deacetylation of histone H3 at 'Lys-36' (H3K36Ac) in the
CC context of nucleosomes. Also mediates deacetylation of non-histone
CC proteins, such as ATM, CDK9, DDX21, DDB1, FBL, FKBP5/FKBP51, GABPB1,
CC RAN, RRP9/U3-55K and POLR1E/PAF53. Enriched in nucleolus where it
CC stimulates transcription activity of the RNA polymerase I complex. Acts
CC by mediating the deacetylation of the RNA polymerase I subunit
CC POLR1E/PAF53, thereby promoting the association of RNA polymerase I
CC with the rDNA promoter region and coding region. In response to
CC metabolic stress, SIRT7 is released from nucleoli leading to
CC hyperacetylation of POLR1E/PAF53 and decreased RNA polymerase I
CC transcription. Required to restore the transcription of ribosomal RNA
CC (rRNA) at the exit from mitosis. Promotes pre-ribosomal RNA (pre-rRNA)
CC cleavage at the 5'-terminal processing site by mediating deacetylation
CC of RRP9/U3-55K, a core subunit of the U3 snoRNP complex. Mediates 'Lys-
CC 37' deacetylation of Ran, thereby regulating the nuclear export of NF-
CC kappa-B subunit RELA/p65. Acts as a regulator of DNA damage repair by
CC mediating deacetylation of ATM during the late stages of DNA damage
CC response, promoting ATM dephosphorylation and deactivation. Suppresses
CC the activity of the DCX (DDB1-CUL4-X-box) E3 ubiquitin-protein ligase
CC complexes by mediating deacetylation of DDB1, which prevents the
CC interaction between DDB1 and CUL4 (CUL4A or CUL4B). Activates RNA
CC polymerase II transcription by mediating deacetylation of CDK9, thereby
CC promoting 'Ser-2' phosphorylation of the C-terminal domain (CTD) of RNA
CC polymerase II. Deacetylates FBL, promoting histone-glutamine
CC methyltransferase activity of FBL (By similarity). Acts as a regulator
CC of mitochondrial function by catalyzing deacetylation of GABPB1 (By
CC similarity). Regulates Akt/AKT1 activity by mediating deacetylation of
CC FKBP5/FKBP51. Required to prevent R-loop-associated DNA damage and
CC transcription-associated genomic instability by mediating deacetylation
CC and subsequent activation of DDX21, thereby overcoming R-loop-mediated
CC stalling of RNA polymerases. In addition to protein deacetylase
CC activity, also acts as protein-lysine deacylase (By similarity). Acts
CC as a protein depropionylase by mediating depropionylation of Osterix
CC (SP7), thereby regulating bone formation by osteoblasts (By
CC similarity). Acts as a histone deglutarylase by mediating
CC deglutarylation of histone H4 on 'Lys-91' (H4K91glu); a mark that
CC destabilizes nucleosomes by promoting dissociation of the H2A-H2B
CC dimers from nucleosomes. Acts as a histone desuccinylase: in response
CC to DNA damage, recruited to DNA double-strand breaks (DSBs) and
CC catalyzes desuccinylation of histone H3 on 'Lys-122' (H3K122succ),
CC thereby promoting chromatin condensation and DSB repair (By
CC similarity). Also promotes DSB repair by promoting H3K18Ac
CC deacetylation, regulating non-homologous end joining (NHEJ). Along with
CC its role in DNA repair, required for chromosome synapsis during
CC prophase I of female meiosis by catalyzing H3K18Ac deacetylation (By
CC similarity). Involved in transcriptional repression of LINE-1
CC retrotransposon via H3K18Ac deacetylation, and promotes their
CC association with the nuclear lamina. Required to stabilize ribosomal
CC DNA (rDNA) heterochromatin and prevent cellular senescence induced by
CC rDNA instability (By similarity). Acts as a negative regulator of SIRT1
CC by preventing autodeacetylation of SIRT1, restricting SIRT1 deacetylase
CC activity (By similarity). {ECO:0000250|UniProtKB:Q8BKJ9,
