Summary: Predicted to enable mRNA 3'-UTR binding activity. Involved in several processes, including embryonic pattern specification; formation of primary germ layer; and negative regulation of macromolecule metabolic process. Located in several cellular components, including P granule; centrosome; and cytosol. Is expressed in several structures, including P0; germ line; head muscle; nerve ring; and oocyte.

PIE-1 SUMOylation promotes germline fates and piRNA-dependent silencing in C. elegans.
Title: PIE-1 SUMOylation promotes germline fates and piRNA-dependent silencing in C. elegans.
Y14 and MAG-1 do not regulate PIE-1 degradation, segregation or synthesis in the early embryo, but do regulate the concentration of maternally-deposited PIE-1::GFP. Taken together, or findings point to an important role for translational control in the regulation of PIE-1 levels in the germline lineage.
Title: PIE-1 Translation in the Germline Lineage Contributes to PIE-1 Asymmetry in the Early Caenorhabditis elegans Embryo.
Results support a heterogeneous reaction/diffusion model for PIE-1 enrichment in which the diffusion coefficient of PIE-1 is reversibly reduced in the posterior, resulting in a stable protein gradient across the zygote at steady state.
Title: Asymmetric enrichment of PIE-1 in the Caenorhabditis elegans zygote mediated by binary counterdiffusion.
These results suggest that PIE-1 uses partially redundant mechanisms to block transcription by targeting both the initiation and elongation phases of the transcription cycle.
Title: Inhibition of transcription by the Caenorhabditis elegans germline protein PIE-1: genetic evidence for distinct mechanisms targeting initiation and elongation.
Degradation of this maternally supplied cell fate determinant is delayed in oma-1 (zu405) mutant embryos.
Title: A gain-of-function mutation in oma-1, a C. elegans gene required for oocyte maturation, results in delayed degradation of maternal proteins and embryonic lethality.
