CC -!- FUNCTION: 3'-5' RNA helicase that plays a key role in the male and
CC female germline by promoting transition from mitotic to meiotic
CC divisions in stem cells (PubMed:28380054, PubMed:28809393,
CC PubMed:29033321, PubMed:29087293, PubMed:29360036, PubMed:32470506).
CC Specifically recognizes and binds N6-methyladenosine (m6A)-containing
CC RNAs, a modification present at internal sites of mRNAs and some non-
CC coding RNAs that plays a role in the efficiency of RNA processing and
CC stability (PubMed:29360036). Essential for ensuring a successful
CC progression of the meiotic program in the germline by regulating the
CC level of m6A-containing RNAs (PubMed:29033321). Acts by binding and
CC promoting degradation of m6A-containing mRNAs: the 3'-5' RNA helicase
CC activity is required for this process and RNA degradation may be
CC mediated by XRN1 exoribonuclease (PubMed:29033321). Required for both
CC spermatogenesis and oogenesis (PubMed:28809393, PubMed:29033321).
CC {ECO:0000269|PubMed:28380054, ECO:0000269|PubMed:28809393,

CC ECO:0000269|PubMed:29360036, ECO:0000269|PubMed:32470506}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.13;
CC Evidence={ECO:0000269|PubMed:29360036};
CC -!- SUBUNIT: Interacts with MEIOC; binds transcripts that regulate the
CC mitotic cell cycle inhibiting progression into metaphase, thereby
CC allowing meiotic prophase to proceed normally (PubMed:28380054,
CC PubMed:29087293). Interacts (via ANK repeats) with XRN1 (By
CC similarity). Interacts with ZCCHC4 (By similarity). Associates with the
CC small ribosomal subunit (By similarity). {ECO:0000250|UniProtKB:Q9H6S0,
CC ECO:0000269|PubMed:28380054, ECO:0000269|PubMed:29087293}.
CC -!- INTERACTION:
CC B2RR83; A2AG06: Meioc; NbExp=4; IntAct=EBI-8572369, EBI-11664020;
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:29033321,
CC ECO:0000269|PubMed:29087293, ECO:0000269|PubMed:29360036}. Cytoplasm,
CC perinuclear region {ECO:0000250|UniProtKB:Q9H6S0}.
CC -!- TISSUE SPECIFICITY: Present in male and female germ cells (at protein
CC level) (PubMed:29033321, PubMed:32470506). Highly expressed in testis
CC (PubMed:28809393, PubMed:29033321, PubMed:29087293, PubMed:29360036).
CC Not detected in spermatogonia next to the tubule wall but is strongly
CC expressed in spermatocytes, suggesting that it is up-regulated in germ
CC cells upon entry into meiosis (at protein level) (PubMed:29087293).
CC {ECO:0000269|PubMed:28809393, ECO:0000269|PubMed:29033321,
CC ECO:0000269|PubMed:29087293, ECO:0000269|PubMed:29360036,
CC ECO:0000269|PubMed:32470506}.
CC -!- DEVELOPMENTAL STAGE: Expression rises between 7 and 12 d.p.p. and
CC remains steady through adulthood. {ECO:0000269|PubMed:28809393}.
CC -!- DOMAIN: The YTH domain mediates RNA-binding. It recognizes and binds
CC N6-methyladenosine (m6A)-containing RNAs.
CC {ECO:0000250|UniProtKB:Q9H6S0}.
CC -!- DISRUPTION PHENOTYPE: Mice are viable and reach adulthood
CC (PubMed:28809393, PubMed:29087293, PubMed:29033321). However, both male
CC and female mice are infertile; male mice have smaller testes, and
CC female mice have smaller ovaries and show progressive loss of germ
CC cells (PubMed:28809393, PubMed:29087293, PubMed:29033321). Mutant germ
CC cells enter meiosis but proceed prematurely to aberrant metaphase and
CC apoptosis, and display defects in transitioning from spermatogonial to
CC meiotic gene expression programs (PubMed:29087293, PubMed:29033321).
CC Mutant testes reveal an up-regulation of N6-methyladenosine (m6A)-
CC enriched transcripts (PubMed:29033321). {ECO:0000269|PubMed:28809393,
CC ECO:0000269|PubMed:29033321, ECO:0000269|PubMed:29087293,
CC ECO:0000269|PubMed:29360036}.
CC -!- MISCELLANEOUS: 'Ketu' is a harbinger of misfortune in Vedic mythology
CC (PubMed:29360036). {ECO:0000303|PubMed:29360036}.
CC -!- SIMILARITY: Belongs to the DEAD box helicase family. DEAH subfamily.
CC {ECO:0000305}.
