CC -!- FUNCTION: Synthetic multivulva class B (synMuvB) protein
CC (PubMed:16678779, PubMed:17075059). SynMuvB proteins are required to
CC repress the induction of vulval development by Ras signaling and
CC probably act by forming the multiprotein DRM complex that represses
CC transcription (PubMed:17075059). Required for the development of sheath
CC cells in the hermaphrodite gonad and for the development of the male
CC spicule, rays and gonad (PubMed:10974557). In association with the zinc
CC finger protein ztf-11, negatively regulates the expression of non-
CC neuronal genes during neurogenesis (PubMed:31386623).
CC {ECO:0000269|PubMed:10974557, ECO:0000269|PubMed:16678779,
CC ECO:0000269|PubMed:17075059, ECO:0000269|PubMed:31386623}.
CC -!- SUBUNIT: Component of the DRM complex, at least composed of lin-9, lin-
CC 35, lin-37, lin-52, lin-53, lin-54- dpl-1 and efl-1 (PubMed:17075059).
CC Interacts with zft-11; the interaction is required to suppress the
CC activation of non-neuronal genes in neurons (PubMed:31386623).
CC {ECO:0000269|PubMed:17075059, ECO:0000269|PubMed:31386623}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=b; Synonyms=LIN-9L;
CC IsoId=P30630-1; Sequence=Displayed;
CC Name=a; Synonyms=LIN-9S;
CC IsoId=P30630-2; Sequence=VSP_007013;
CC -!- DISRUPTION PHENOTYPE: Decreased protein levels of DRM complex
CC components including lin-37, lin-52 and lin-54 (PubMed:17075059).
CC Double knockout with the programmed cell death regulator mcd-1 results
CC in 100% lethality during the L1 stage of larval development
CC (PubMed:17237514). RNAi-mediated knockdown in a ced-1 mutant background
CC results in reduced somatic cell apoptosis (PubMed:27650246).
CC {ECO:0000269|PubMed:17075059, ECO:0000269|PubMed:17237514,
CC ECO:0000269|PubMed:27650246}.
CC -!- SIMILARITY: Belongs to the lin-9 family. {ECO:0000305}.
