Dioxygenase that mediates demethylation of DNA and RNA containing 1-methyladenosine (m1A). Repairs alkylated DNA containing 1-methyladenosine (m1A) and 3-methylcytosine (m3C) by oxidative demethylation. Has a strong preference for single-stranded DNA. Able to process alkylated m3C within double-stranded regions via its interaction with ASCC3, which promotes DNA unwinding to generate single-stranded substrate needed for ALKBH3. Also acts on RNA. Demethylates N(1)-methyladenosine (m1A) RNA, an epigenetic internal modification of messenger RNAs (mRNAs) highly enriched within 5'-untranslated regions (UTRs) and in the vicinity of start codons. Requires molecular oxygen, alpha-ketoglutarate and iron.

These data highlight a novel role for ALKBH3 in tumor progression via RNA demethylation and subsequent protein synthesis promotion. PMID: 28205560
ALKBH3 is a novel addition to the catalogue of DNA repair genes found inactivated in breast cancer. Our results underscore a link between defective alkylation repair and breast cancer which, additionally, is found in association with poor disease outcome. PMID: 28679371
The TP53 knockout shifted the phenotypes of A549 cells induced by ALKBH3 knockdown from cell cycle arrest to apoptosis induction, suggesting that the TP53 gene status is a critical determinant of the phenotypes induced by ALKBH3 knockdown in NSCLC cells. PMID: 28479246
These results revealed that N3-ethylthymidine , but not other DNA lesions, could be repaired by Alkbh2 and Alkbh3 in mammalian cells. PMID: 26930515
Results show that PCA1 expression was positively correlated with advanced stages in renal cell carcinoma and strongly suggest that PCA-1 may be functionally important and a novel molecular target for human renal cell carcinoma. PMID: 26035443
