Transcription factor which binds to enhancer elements in the promoter region of genes (PubMed:26234645). Regulates the expression of the transcription factor bed-3 to control vulval development (PubMed:26234645, PubMed:32417234). Promotes terminal differentiation in the hypodermis and is involved in regulation of gonadal outgrowth and entry into the dauer stage (PubMed:24613396). Regulates the timing of dorsalward migration of the distal tip cells of the hermaphrodite gonad by inhibiting precocious unc-5 and lin-29 expression which in turn prevents early dorsalward turning (PubMed:24968003). Plays a role in male tail tip morphogenesis (PubMed:21408209). Interacts with dre-1; the interaction targets blmp-1 for proteasomal degradation (PubMed:24613396, PubMed:24968003). Interacts with ldb-1 and ham-3 (PubMed:32417234). Localizes to the nucleus and cytoplasm in hyp8-11 tail tip cells throughout development, but cytoplasmic localization is most prominent during male tail tip retraction. Expressed in hypodermal, vulval, intestinal and distal tip cells. In distal tip cells, expressed from mid-L2 when gonadal outgrowth initiates (PubMed:24613396). By mid-L3, just prior to the dorsal gonadal turn, levels drop dramatically (PubMed:24968003). In seam and hypodermal cells, levels are largely constant throughout larval development except for a transient peak early in L4 (PubMed:24613396). Ubiquitinated by the SCF(dre-1) complex, leading to its degradation by the proteasome. Gonadal migration defects with premature dorsal turning of distal tip cells in the hermaphrodite gonad (PubMed:24613396, PubMed:24968003). Defective dauer formation, shortened lifespan and retarded terminal differentiation of seam cells with incomplete adult alae synthesis (PubMed:24613396). Suppresses the precocious seam cell terminal differentiation and gonadal migration defects seen in dre-1 mutants (PubMed:24613396). Weak dumpy phenotype and partially penetrant embryonic lethality (PubMed:24968003). Reduced expression of the transcription factor bed-3 which is involved in vulval development and failed division of vulval precursor cell descendents (PubMed:26234645). RNAi-mediated knockdown impairs the expression of several hypodermis-specific genes; reduces levels of clo-124 mRNA and increases levels of lin-29 mRNA (PubMed:32417234). RNAi-mediated knockdown results in the precocious onset of tail tip retraction resulting in over-retracted and shortened adult male tails (also known as the Ore phenotype) (PubMed:21408209).
