CC -!- FUNCTION: Male determiner protein (M-factor) that controls male somatic
CC sexual differentiation. Acts as a dominant factor that regulates the
CC mRNA splicing of transformer (tra) and doublesex (dsx) transcripts and
CC promotes expression of male splice forms of tra and dsx (By
CC similarity). Probably acts as a component of the spliceosome C complex
CC required for mRNA splicing factor and exon-junction complex (EJC)
CC assembly (By similarity). Hinders eIF4AIII from non-specifically
CC binding RNA and escorts it to the splicing machinery to promote EJC
CC assembly on mature mRNAs (By similarity).
CC {ECO:0000250|UniProtKB:P0DP78, ECO:0000250|UniProtKB:Q9HCG8}.
CC -!- SUBUNIT: Component of the spliceosome C complex.
CC {ECO:0000250|UniProtKB:Q9HCG8}.
CC -!- SUBCELLULAR LOCATION: Nucleus speckle {ECO:0000250|UniProtKB:Q9HCG8}.
CC -!- DEVELOPMENTAL STAGE: Specifically expressed in early male embryos.
CC Zygotic expression first appears in 2- to 3-hour-old embryos
CC (cellularized blastoderm stage). Expression is then maintained
CC throughout male development until adulthood.
CC {ECO:0000269|PubMed:28495751}.
CC -!- MISCELLANEOUS: The M.domestica genome only codes for one male
CC determiner Mdmd protein, which is encoded in the M region, and can be
CC located at different loci on the genome (chromosomes II, III, V or Y).
CC The M region contains a cluster of tandemly repeated Mdmd copies with
CC only one intact copy: other copies are degenerate with large
CC truncations and frameshifts and are assumed to be non-functional. The
CC presence of multiple copies in the M region may preserve its integrity
CC in a hostile non-recombining environment. This protein is encoded on
CC chromosome II. {ECO:0000269|PubMed:28495751}.
CC -!- SIMILARITY: Belongs to the CWC22 family. {ECO:0000305}.
