Bloom syndrome protein is a protein that in humans is encoded by the BLM gene and is not expressed in Bloom syndrome.[1]

The Bloom syndrome gene product is related to the RecQ subset of DExH box-containing DNA helicases and has both DNA-stimulated ATPase and ATP-dependent DNA helicase activities. Mutations causing Bloom syndrome delete or alter helicase motifs and may disable the 3' → 5' helicase activity. The normal protein may act to suppress inappropriate homologous recombination.[2]


Bloom syndrome protein has been shown to interact with CHEK1,[3] Replication protein A1,[4][5][6] Werner syndrome ATP-dependent helicase,[7] RAD51L3,[8] Ataxia telangiectasia mutated,[9][10] RAD51,[11] XRCC2,[8] Flap structure-specific endonuclease 1,[12] H2AFX,[3] TP53BP1,[3] FANCM,[13] P53,[3][14][15][16] TOP3A,[4][17][18][19] MLH1[9][18][20][21] and CHAF1A.[22]
