Biol. 10:223-226(2000). CC -!- FUNCTION: Core histone-binding subunit that may target chromatin CC assembly factors, chromatin remodeling factors and histone CC deacetylases to their histone substrates in a manner that is CC regulated by nucleosomal DNA (By similarity). Essential protein. CC Required to repress the induction of vulval development by Ras CC signaling. CC -!- SUBUNIT: Binds directly to helix 1 of the histone fold of histone CC H4, a region that is not accessible when H4 is in chromatin (By CC similarity). Probable component of the NuRD complex, composed of CC at least lin-35, lin-53 and hda-1. CC -!- SUBCELLULAR LOCATION: Nucleus. CC -!- DEVELOPMENTAL STAGE: Ubiquitously expressed in embryos and newly CC hatched larvae. Expressed in all P(3-8).p cells at the time of CC vulval induction. CC -!- SIMILARITY: Belongs to the WD repeat RBAP46/RBAP48/MSI1 family. CC -!- SIMILARITY: Contains 6 WD repeats.
