ALKBH5 — AlkB homolog 5, RNA demethylase

ALKBH5 belongs to a gene co-expression module in 2 of 28 SCUBA cell types. Each module groups genes that rise and fall together in that cell type; the genes it shares a module with are its closest co-expression partners there.

About the gene

Function

Dioxygenase that specifically demethylates N(6)- methyladenosine (m6A) RNA, the most prevalent internal modification of messenger RNA (mRNA) in higher eukaryotes. Demethylates RNA by oxidative demethylation, which requires molecular oxygen, alpha- ketoglutarate and iron. Demethylation of m6A mRNA affects mRNA processing, translation and export. Can also demethylate N(6)-methyladenosine in single-stranded DNA (in vitro). Required for the late meiotic and haploid phases of spermatogenesis by mediating m6A demethylation in spermatocytes and round spermatids: m6A demethylation of target transcripts is required for correct splicing and the production of longer 3'-UTR mRNAs in male germ cells (By similarity). Involved in paraspeckle assembly, a nuclear membraneless organelle, by undergoing liquid-liquid phase separation. Paraspeckle assembly is coupled with m6A demethylation of RNAs, such as NEAT1 non-coding RNA. Also acts as a negative regulator of T-cell development: inhibits gamma-delta T-cell proliferation via demethylation of JAG1 and NOTCH2 transcripts (By similarity). Inhibits regulatory T-cell (Treg) recruitment by mediating demethylation and destabilization of CCL28 mRNAs (By similarity).
