wdr-5.1 encodes a WD40 repeat-containing protein that is the C. elegans ortholog of mammalian WDR5, a member of a conserved H3K4 trimethylation (H3K4me3) complex; WDR-5.1 functions to regulate H3K4 methylation levels and to negatively regulate adult worm lifespan; WDR-5.1 activity also antagonizes SynMuv transcriptional repressors; WDR-5.1 is broadly expressed beginning at the 20-cell stage of embryogenesis with continuing expression seen, albeit more restricted, through adulthood; WDR-5.1 localizes to the nucleus.
Enables RNA polymerase II-specific DNA-binding transcription factor binding activity. Involved in determination of adult lifespan; programmed cell death; and transdifferentiation. Located in cytoplasm and nucleus. Part of MLL3/4 complex. Expressed in several structures, including P3.p hermaphrodite; P4.p hermaphrodite; hermaphrodite gonad; neurons; and somatic gonad precursor. Is an ortholog of human WDR5 (WD repeat domain 5).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
