Our Abpromise guarantee covers the use of ab476 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/2000. Detects a band of approximately 170 kDa (predicted molecular weight: 159 kDa). We have conflicting reports from customers about whether this antibody works in IF in HeLa or SK-N-SH cells. We would appreciate any customer feedback about this antibody.|
|IP||Use at an assay dependent dilution.|
|ICC||Use at an assay dependent dilution.|
功能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.
疾病相关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.
序列相似性Belongs to the helicase family. RecQ subfamily.
Contains 1 helicase ATP-binding domain.
Contains 1 helicase C-terminal domain.
Contains 1 HRDC domain.
翻译后修饰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.
