Target
-
Function
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. -
Involvement in disease
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. -
Sequence similarities
Belongs to the helicase family. RecQ subfamily.
Contains 1 helicase ATP-binding domain.
Contains 1 helicase C-terminal domain.
Contains 1 HRDC domain. -
Post-translational
modificationsPhosphorylated in response to DNA damage. Phosphorylation requires the FANCA-FANCC-FANCE-FANCF-FANCG protein complex, as well as the presence of RMI1. -

Immunoprecipitation - Anti-Blooms Syndrome Protein Blm antibody (ab476)Image from S Raynard et al, J Biol Chem 281:13861-4 (2006), Fig 2.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.
