    Participates in DNA replication and repair. Exhibits a magnesium-dependent ATP-dependent DNA-helicase activity that unwinds single- and double-stranded DNA in a 3'-5' direction.
  • 関連疾患
    Defects in BLM are the cause of Bloom syndrome (BLM) [MIM:210900]. BLM is an autosomal recessive disorder characterized by proportionate pre- and postnatal growth deficiency, sun-sensitive telangiectatic hypo- and hyperpigmented skin, predisposition to malignancy, and chromosomal instability.
  • 配列類似性
    Belongs to the helicase family. RecQ subfamily.
    Contains 1 helicase ATP-binding domain.
    Contains 1 helicase C-terminal domain.
    Contains 1 HRDC domain.
  • 翻訳後修飾
    Phosphorylated in response to DNA damage. Phosphorylation requires the FANCA-FANCC-FANCE-FANCF-FANCG protein complex, as well as the presence of RMI1.

  • BLAP75 physically interacts with BLM and Topo IIIa. Purified BLM was incubated with purified Topo IIIa and the reaction mixture was subjected to Immunoprecipitation with ab476. The reaction supernatant (S), wash (W), and eluate (E) were analyzed by SDS-PAGE, GST-BLAP75 or GST alone was incubated with BLM. Protein complexes were captured on glutathione-Sepharose beads, followed by SDS-PAGE.

Question
Answer

Thank you for your call today and for letting us know about the trouble with the new lot of this antibody.

As we discussed, I'm sending a free of charge vial from a new lot of the antibody on order *** which should arrive early next week. Please keep me updated about the results with this replacement vial.

I will also contact the lab to see if there is any more information they may have. Please let me know if you have further questions or if there is anything else that we can do for you, and I'll be happy to help.

Answer

As stated on the datasheet, "Cross reactivity with blm from other species has not been tested but is highly likely against mammalian homologues of human blm."

Answer

The blot shown on the datasheet is using HeLa Nuclear extracts, not whole cell extracts. However, there are several things to bear in mind: 1- It may be possible to dilute the antibody a bit more: We have used it at 1:2500 with good results. 2- Blm is very sensitive to degradation... so extracts must be done carefully. A useful control could be cells that are lysed directly in a buffer containing 6 M Urea, 20 mM Tris ph 7.5, sonicate for 10 seconds, and centrifugue for 5 min at 13000rpms in an micro-centrifugue (and take the supernatant). If you make extracts for IPs, the protein can be easily degraded, with this control you avoid that. 3- Sometimes it helps to strip the blot before blocking (and, of course before the incubation with the primary antibody).
