RT complex.";

CC -!- FUNCTION: The METTL3-METTL14 heterodimer forms a N6-methyltransferase
CC complex that methylates adenosine residues at the N(6) position of some
CC RNAs and regulates various processes such as the circadian clock,
CC differentiation of embryonic and hematopoietic stem cells, cortical
CC neurogenesis, response to DNA damage, differentiation of T-cells and
CC primary miRNA processing (PubMed:22575960, PubMed:24284625,
CC PubMed:25719671, PubMed:25799998, PubMed:26321680, PubMed:26593424,
CC PubMed:27627798, PubMed:27373337, PubMed:27281194, PubMed:28297716,
CC PubMed:30428350, PubMed:29506078, PubMed:29348140, PubMed:9409616). In
CC the heterodimer formed with METTL14, METTL3 constitutes the catalytic
CC core (PubMed:27627798, PubMed:27373337, PubMed:27281194). N6-
CC methyladenosine (m6A), which takes place at the 5'-[AG]GAC-3' consensus
CC sites of some mRNAs, plays a role in mRNA stability, processing,
CC translation efficiency and editing (PubMed:22575960, PubMed:24284625,
CC PubMed:25719671, PubMed:25799998, PubMed:26321680, PubMed:26593424,
CC PubMed:28297716, PubMed:9409616). M6A acts as a key regulator of mRNA
CC stability: methylation is completed upon the release of mRNA into the
CC nucleoplasm and promotes mRNA destabilization and degradation
CC (PubMed:28637692). In embryonic stem cells (ESCs), m6A methylation of
CC mRNAs encoding key naive pluripotency-promoting transcripts results in
CC transcript destabilization, promoting differentiation of ESCs (By
CC similarity). M6A regulates the length of the circadian clock: acts as
CC an early pace-setter in the circadian loop by putting mRNA production
CC on a fast-track for facilitating nuclear processing, thereby providing
CC an early point of control in setting the dynamics of the feedback loop
CC (By similarity). M6A also regulates circadian regulation of hepatic
CC lipid metabolism (PubMed:30428350). M6A regulates spermatogonial
CC differentiation and meiosis and is essential for male fertility and
CC spermatogenesis (By similarity). Also required for oogenesis (By
CC similarity). Involved in the response to DNA damage: in response to
CC ultraviolet irradiation, METTL3 rapidly catalyzes the formation of m6A
CC on poly(A) transcripts at DNA damage sites, leading to the recruitment
CC of POLK to DNA damage sites (PubMed:28297716). M6A is also required for
CC T-cell homeostasis and differentiation: m6A methylation of transcripts
CC of SOCS family members (SOCS1, SOCS3 and CISH) in naive T-cells
CC promotes mRNA destabilization and degradation, promoting T-cell
CC differentiation (By similarity). Inhibits the type I interferon
CC response by mediating m6A methylation of IFNB (PubMed:30559377). M6A
CC also takes place in other RNA molecules, such as primary miRNA (pri-
CC miRNAs) (PubMed:25799998). Mediates m6A methylation of Xist RNA,
CC thereby participating in random X inactivation: m6A methylation of Xist
CC leads to target YTHDC1 reader on Xist and promote transcription
CC repression activity of Xist (PubMed:27602518). M6A also regulates
CC cortical neurogenesis: m6A methylation of transcripts related to
CC transcription factors, neural stem cells, the cell cycle and neuronal
CC differentiation during brain development promotes their destabilization
CC and decay, promoting differentiation of radial glial cells (By
CC similarity). METTL3 mediates methylation of pri-miRNAs, marking them
CC for recognition and processing by DGCR8 (PubMed:25799998). Acts as a
CC positive regulator of mRNA translation independently of the
CC methyltransferase activity: promotes translation by interacting with
CC the translation initiation machinery in the cytoplasm
CC (PubMed:27117702). Its overexpression in a number of cancer cells
CC suggests that it may participate in cancer cell proliferation by
CC promoting mRNA translation (PubMed:27117702). During human coronorivus
CC SARS-CoV-2 infection, adds m6A modifications in SARS-CoV-2 RNA leading
CC to decreased RIGI binding and subsequently dampening the sensing and
CC activation of innate immune responses (PubMed:33961823).

CC via a sequence pairing mechanism (By similarity). Methyltransferase
CC activity is inhibited by sumoylation (PubMed:29506078).

CC -!- SUBUNIT: Heterodimer; heterodimerizes with METTL14 to form an
CC antiparallel heterodimer that constitutes an active methyltransferase
CC (PubMed:27627798, PubMed:27373337, PubMed:27281194). Component of the
CC WMM complex, a N6-methyltransferase complex composed of a catalytic
CC subcomplex, named MAC, and of an associated subcomplex, named MACOM

CC METTL3 and METTL14 (PubMed:24407421, PubMed:24981863, PubMed:27602518,
CC PubMed:29507755). The MACOM subcomplex is composed of WTAP, ZC3H13,
CC CBLL1/HAKAI, VIRMA, and, in some cases of RBM15 (RBM15 or RBM15B)
CC (PubMed:27602518, PubMed:29507755). Interacts with NCBP1/CBP80

CC pre-mRNA splicing components (PubMed:9409616). In response to
CC ultraviolet irradiation, colocalizes to DNA damage sites however, it
CC probably does not bind DNA but localizes in the vicinity of DNA damage

CC -!- TISSUE SPECIFICITY: Widely expressed at low level. Expressed in spleen,
CC thymus, prostate, testis, ovary, small intestine, colon and peripheral
CC blood leukocytes. {ECO:0000269|PubMed:9409616}.
CC -!- INDUCTION: Overexpressed in a number of cancer tissues, such as lung
CC adenocarcinoma and colon adenocarcinoma (PubMed:27117702).
CC {ECO:0000269|PubMed:27117702}.
CC -!- DOMAIN: Gate loop 1 and gate loop 2 regions are adjacent to the S-
CC adenosyl-L-homocysteine-binding site and display large conformational
CC changes upon ligand-binding. They may play an important role in
CC adenosine recognition. The interface loop contributes to the
CC heterodimer interaction. {ECO:0000269|PubMed:27281194}.
CC -!- PTM: Sumoylation inhibits the N6-adenosine-methyltransferase activity.
CC Sumoylation does not affect subcellular location or interaction with
CC METTL14. Desumoylated by SENP1. {ECO:0000269|PubMed:29506078}.
CC -!- SIMILARITY: Belongs to the MT-A70-like family. {ECO:0000255|PROSITE-
