Regulates diverse developmental processes including larval molting and gonad maturation. Promotes the localization of myrf-1 and myrf-2 to the cell membrane (PubMed:33950834). In association with myrf-1, promotes the synaptic remodeling of DD GABAergic motor neurons whereby new synapses form in the dorsal processes of DD neurons (PubMed:33950834). Interacts with glh-1 (PubMed:22342905). Interacts (via LRR regions) with myrf-1 (via C-terminus); the interaction promotes the role of myrf-1 in the synaptic remodeling of DD GABAergic motor neurons at the cell membrane (PubMed:33950834). Detected throughout the cytoplasm in germline and somatic blastomeres during embryogenesis and in germline and somatic tissue in adult hermaphrodites. Localizes to P-granules in L1 larval Z2 and Z3 germline precursor cells. Expression in P-granules is most pronounced during the meiotic stage of the germline; in mature oocytes and sperm expression switches to a cytoplasmic pattern. Expressed in the germline and somatic cells (PubMed:22342905). Expressed in the germline and somatic cells (PubMed:22342905). Expressed at higher levels in germline cells relative to somatic cells (PubMed:22342905). Expressed in germline cells (PubMed:22342905). Highly expressed in the pharynx and at lower levels in the intestine, but not detected in other tissues (PubMed:22342905). Other studies suggest a broader expression pattern in somatic tissues: from embryogenesis to adult stages, expressed strongly in body wall muscle, vulva, somatic gonad and pharynx, at lower levels in the nerve ring, hypodermis, and rectal epithelia, and very weakly in the intestine (PubMed:23682709). Expressed at all developmental stages from embryos undergoing morphogenesis to gravid adults (PubMed:23682709). Broadly expressed in embryos and early larvae, but expression decreases in late larvae and adults (PubMed:33950834). Expressed in seam cells during larval development (PubMed:33950834). Expressed in DD GABAergic motor neurons in L1 and L2 stage larva (PubMed:33950834). During larval stage L1, expressed in the pharynx and in intestinal cells (PubMed:22342905). Expressed most strongly during mid-to-late intermolt periods (at protein level) (PubMed:23682709). Larval lethal. Animals developmentally arrest prior to the first larval molt and subsequent growth is slow, although larvae survive for up to 8 days at 20 degrees Celsius. Animals also display uncoordinated locomotion, a shortened cuticle, pharyngeal defects, stunted gonad development, and abnormal vulval morphogenesis. Heterozygous worms have reduced brood sizes. Knockout in DD GABAergic motor neurons results in defective synaptic remodeling of DD GABAergic motor neurons (PubMed:33950834). RNAi-mediated knockdown in the germline, results in sterility and gametogenesis phenotypes including complete absence of oocytes, endomitotically replicating oocytes, and failure to lay eggs. Animals surviving to the L4 stage have hypodermal defects including lack of lateral alae and incomplete seam cell fusion, and fail to express col-19 and mlt-10. RNAi-mediated knockdown in lin-29 null mutants results in partial suppression of the molting and vulval RNAi phenotypes in L4 stage larvae.
