26582912 Different charge distributions along the DNA binding groove may account for the drastic difference in processivity and DNA digestion efficiency, including that of damaged substrates, between SNM1A and SNM1B.
23863462 The SNM1B/APOLLO DNA nuclease functions in resolution of replication stress and maintenance of common fragile site stability.
23189151 the N-terminal region of Snm1B forms a complex containing PSF2 and Mus81, while the C-terminal region is important for PSF2-mediated chromatin association.
22907656 The nuclease hSNM1B/Apollo is linked to the Fanconi anemia pathway via its interaction with FANCP/SLX4.
22692201 differences in the substrate selectivities of SNM1A and SNM1B are likely to be relevant to their in vivo roles
21478198 SNM1B functions epistatically to the central Fanconi anemia factor, FANCD2, in cellular survival after interstrand crosslinks damage and homology-directed repair of DNA double-strand breaks
20655466 TRF2, which binds preferentially to positively supercoiled DNA substrates, together with Apollo, negatively regulates the amount of TOP1, TOP2alpha, and TOP2beta at telomeres.
19411856 DCLRE1B protein binds to a C-terminal fragment of HSP72 Heat-Shock Proteins, known to contain the substrate binding domain.
19197158 Results suggest that SNM1B/Apollo and Astrin function together to enforce the prophase checkpoint in response to spindle stress.
18593705 The protein hSnm1B is stabilized when bound to the telomere-binding protein TRF2
18469862 Snm1B interacts with the Mre11-Rad50-Nbs1 (MRN) complex and with FancD2 further substantiating its role as a checkpoint/DNA repair protein.
18468965 observations suggest an important role for hSNM1B in the response to ionizing radiation damage, a role that may be, in part, upstream of the central player in maintenance of genome integrity, ATM
16730176 SNM1B (Apollo) is an Artemis-like nuclease that is required for the protection of telomeres during or after their replication. [Apollo]
16730175 SNM1B (Apollo) protein exhibits a 5'-to-3' DNA exonuclease activity and functions together with TRF2 to protect telomeres from damage and fusion.
16606622 the C terminus of Snm1B was shown to interact with the TRF homology domain of TRF2 indicating that Snm1B is likely recruited to the telomere via interaction with the double-stranded telomere-binding protein TRF2
15467758 siRNA knockdown of hSNM1B rendered cells sensitive to ionizing radiation, suggesting the possibility of hSNM1B involvement in homologous recombination repair of double-strand breaks arising as intermediates of ICL repair
