Feldhahn, Ferretti, Robbiani, Callen, Deroubaix, Selleri, Nussenzweig, Nussenzweig: The hSSB1 orthologue Obfc2b is essential for skeletogenesis but dispensable for the DNA damage response in vivo. in The EMBO journal 2012
This study identified SSBP1 as a putative N6-methyldeoxyadenosine binding protein.
NEIL1 and homotetrameric mtSSB form a larger ternary complex in presence of DNA, however, the tetrameric form of mtSSB gets disrupted by NEIL1 in the absence of DNA as revealed by the formation of a smaller NEIL1-mtSSBmonomer complex.
These results indicated that SSDBP1 may induce cell chemoresistance of cisplatin through promoting DNA repair, resistance-related gene expression, cell proliferation, and inhibiting apoptosis.
Data show that single-stranded DNA binding protein 1 (hSSB1/NABP2/OBFC2B) forms a tetramer and is stabilized by two cysteines (C81 and C99) as well as a subset of charged and hydrophobic residues.
DNA synthesis determines the binding mode of the human mtSSB.
The data presented in this study suggests that while SSBP1 has predominantly been considered in a DNA repair context, it is likely to have roles in many other cellular processes. In particular, the identification of numerous proteins with roles in mRNA metabolism, transcriptional transactions and ribosomal processes, may suggest these as important areas of SSBP1 function.
Data suggest that human mitochondrial SSB shares many physicochemical properties with E coli SSB and that the differences may be explained by the lack of an acidic, disordered C-terminal tail in human mitochondrial SSB protein. (SSB = single-stranded DNA-binding protein)
Data suggest that human mitochondrial SSB and E coli SSB both protect and expose single-stranded DNA; implications from these studies toward understanding DNA replication and DNA repair abound. (SSB = single-stranded DNA-binding protein) [EDITORIAL]
hSSB1 is directly phosphorylated by DNA-PK at serine residue 134. While this modification is largely suppressed in undamaged cells by PPP-family protein phosphatases, S134 phosphorylation is enhanced following the disruption of replication forks and promotes cellular survival.
The stimulatory effect of mtSSB on Pol gamma on these ssDNA templates is not species-specific.
This study determined that hSSB1 acetylation at K94 mediated by the acetyltransferase p300 and the deacetylases SIRT4 and HDAC10 impaired its ubiquitin-mediated degradation by proteasomes.
SSBP1 protects cells from proteotoxic stresses by potentiating stress-induced HSF1 transcriptional activity
Fbxl5 interacts with and targets hSSB1 for ubiquitination and degradation, which could be prevented by ATM-mediated hSSB1 T117 phosphorylation.
In response to the DNA damage response, INTS3-hSSB1-INTS6 complex relocates to the DNA damage sites.
Results indicate that hSSB1 may regulate DNA damage checkpoints by positively modulating p53 and its downstream target p21.
mtSSB potentially prevents formation of DNA breaks in ssDNA, ensuring that base removal primarily occurs in dsDNA.
Local enrichment of UNG1 at DNA-bound mtSSB may furthermore facilitate rapid access to- and processing of the damage once the dsDNA conformation is restored.
mtSSB uses distinct structural elements to interact functionally with its mtDNA replisome partners and to promote proper mtDNA replication in animal cells
hSSB1 may positively modulate p21 to regulate cell cycle progression and DNA damage response, implicating hSSB1 as a novel, promising therapeutic target for cancers such as hepatocellular carcinoma
Results describe the role of mitochondrial single-stranded DNA binding protein in the maintenance of mitochondrial DNA in cultured human cells.
SSBP1 was down-regulated by Angiotensin II and implicated in cardiac fibrosis through fibroblast proliferation and collagen expression partly via the p53 protein.
SSBp1 deletion results in increased chromosomal aberrations and localizes to telomeres and participate in the repair of uncapped telomeres.
plays a role in the regulation of mitochondrial morphology. (review)
overexpression of Mitogenin I or mitochondrial single-stranded DNA-binding protein increased elongated or fragmented mitochondria in mouse C2C12 myoblast cells, respectively.
SSBP1 is a housekeeping gene involved in mitochondrial biogenesis (Tiranti et al., 1995
