Background Information

DBR1(Lariat debranching enzyme) hydrolyzes 2-prime-to-5-prime branched phosphodiester bonds at the branch point of excised lariat intron RNA and converts them into linear molecules. DBR1 belongs to the lariat debranching enzyme family. Inhibiton of Dbr1 can suppress TDP-43 toxicity in primary neurons, suggesting that Dbr1 could be a potential therapeutic target for ALS and related TDP-43 proteinopathies (PMID: 23104007). This protein has 2 isoforms produced by alternative splicing.

Aiswarya (Verified Customer) (12-23-2019)

The Dbr1 antibody was used to check knock down of Dbr1 and worked well. Additional non specific bands come up but do not interfere in the specific size range.

  • Applications: Western Blot,
  • Primary Antibody Dilution: 1:1000
  • Cell Tissue Type: HAP1, HEK293
