SIRT1

Enzymes, Metabolic proteins

Intracellular

Cell type enriched (Early spermatids)

Low immune cell specificity

Low cell line specificity

Interacts with XBP1 isoform 2 (PubMed:20955178). Found in a complex with PCAF and MYOD1. Interacts with FOXO1; the interaction deacetylates FOXO1, resulting in its nuclear retention and promotion of its transcriptional activity Component of the eNoSC complex, composed of SIRT1, SUV39H1 and RRP8. Interacts with HES1, HEY2 and PML. Interacts with RPS19BP1/AROS. Interacts with CCAR2 (via N-terminus); the interaction disrupts the interaction between SIRT1 and p53/TP53. Interacts with SETD7; the interaction induces the dissociation of SIRT1 from p53/TP53 and increases p53/TP53 activity. Interacts with MYCN, NR1I2, CREBZF, TSC2, TLE1, FOS, JUN, NR0B2, PPARG, NCOR, IRS1, IRS2 and NMNAT1. Interacts with HNF1A; the interaction occurs under nutrient restriction. Interacts with SUZ12; the interaction mediates the association with the PRC4 histone methylation complex which is specific as an association with PCR2 and PCR3 complex variants is not found. Interacts with BCL6; leads to a epigenetic repression of specific target genes. Interacts with CLOCK, ARNTL/BMAL1 and PER2 (By similarity). Interacts with PPARA; the interaction seems to be modulated by NAD(+) levels (PubMed:24043310). Interacts with NR1H3 and this interaction is inhibited in the presence of CCAR2. Interacts with CHEK2. Interacts with p53/TP53. Exhibits a preferential interaction with sumoylated CCAR2 over its unmodified form. Interacts with PACS2 (PubMed:29656858). Interacts with SIRT7 (By similarity). Interacts with PUS7 (PubMed:31451225). (Microbial infection) Interacts with HIV-1 Tat.
