CC       complex that methylates adenosine residues at the N(6) position of some

CC       differentiation of embryonic and hematopoietic stem cells, cortical

CC       the heterodimer formed with METTL14, METTL3 constitutes the catalytic
CC       core (PubMed:27281194, PubMed:27373337, PubMed:27627798). 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 coronavirus
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).
