Gene Group (FlyBase)
M6A METHYLTRANSFERASE COMPLEX -
The m6A methyltransferase complex is a nuclear, multi-component enzyme involved in mediating N6-methyladenosine (m6A) modification in mRNAs. This modification modulates mRNA processing and activity. (Adapted from FBrf0234210 and FBrf0234211).
Pathway (FlyBase)
Positive Regulators of Wnt-TCF Signaling Pathway -
Positive regulators of canonical Wnt signaling up-regulate the pathway, resulting in the enhancement of transcriptional regulation mediated by β-catenin (arm).
Protein Function (UniProtKB)
RNA-binding protein that acts as an associated component of the WMM complex, a complex that mediates N6-methyladenosine (m6A) methylation of mRNAs (PubMed:27919077, PubMed:29535189, PubMed:29555755). M6a modification plays a role in the efficiency of mRNA splicing and is required for sex determination (PubMed:27919077, PubMed:29535189, PubMed:29555755). In the WMM complex, may act by binding target RNAs and recruiting the WMM complex (PubMed:29535189). Required for sex determination and dosage compensation via Sxl alternative splicing: m6A methylation acts as a key regulator of Sxl pre-mRNA and promotes female-specific alternative splicing of Sxl, which determines female physiognomy (PubMed:26324914, PubMed:29535189, PubMed:29555755). M6A methylation is also required for neuronal functions (PubMed:27919077). Acts as a positive regulator of canonical Wg signaling during wing disk and eye development (PubMed:16547102, PubMed:18174108).

Subunit Structure (UniProtKB)
Component of the WMM complex, a N6-methyltransferase complex composed of a catalytic subcomplex, named MAC, and of an associated subcomplex, named MACOM (PubMed:27919077, PubMed:29535189, PubMed:28675155, PubMed:29555755). The MAC subcomplex is composed of Ime4/Mettl3 and Mettl14 (PubMed:27919077, PubMed:29535189, PubMed:28675155, PubMed:29555755). The MACOM subcomplex is composed of fl(2)d, Flacc/Xio, Hakai, vir, and, in some cases of nito (PubMed:27919077, PubMed:29535189, PubMed:29555755). Interacts with Sxl (PubMed:26324914). Interacts with Hipk; leading to phosphorylation (PubMed:25040100).
(UniProt, Q7KMJ6)
Post Translational Modification
Phosphorylated by Hipk at Ser-23, Ser-25 and/or Ser-27; the precise position if phosphorylation sites is unknown (PubMed:25040100).
