The function of ENSG00000125652 (ALKBH7, alkB homolog 7, RNA demethylase) is as follows. RNA demethylase that demethylates N(2)-dimethylguanosine and N(1)-methyladenosine within mitochondrial pre-tRNA regions. This demethylation activity plays a crucial role in regulating the processing of nascent polycistronic mitochondrial RNA, thereby influencing mitochondrial gene expression and overall mitochondrial activity (PubMed:34253897). In response to extensive DNA damage is required for programmed necrosis induced by alkylation and oxidation. Acts by triggering the collapse of mitochondrial membrane potential and loss of mitochondrial function that leads to energy depletion and cell death (PubMed:23666923). Involved in fatty acid metabolism (By similarity). {ECO:0000250|UniProtKB:Q9D6Z0, ECO:0000269|PubMed:23666923, ECO:0000269|PubMed:34253897}.
