| | trm-1 | tRNA (guanine(26)-N(2))-dimethyltransferase; Dimethylates a single guanine residue at position 26 of most tRNAs using S-adenosyl-L-methionine as donor of the methyl groups. (526 aa) |
| | spn-4 | RRM domain-containing protein. (351 aa) |
| | oma-2 | CCCH-type zinc finger protein oma-2; Zinc-finger RNA-binding protein that binds to 5'-UA[AU]-3' motifs in the 3'-UTR of maternal mRNAs to suppress translation in oocytes and embryos. Acts redundantly with oma-1 to control the temporal expression and distribution of maternal proteins and thereby promote meiotic progression, oocyte maturation, fertilization and embryonic development. Also, together with oma-1, is involved in P-granule distribution during embryonic development. (393 aa) |
| | frg-1 | Protein FRG1 homolog; Binds to mRNA in a sequence-independent manner. May play a role in regulation of pre-mRNA splicing or in the assembly of rRNA into ribosomal subunits. May be involved in mRNA transport. May be involved in epigenetic regulation of muscle differentiation through regulation of activity of the histone-lysine N-methyltransferase KMT5B (By similarity); Belongs to the FRG1 family. (274 aa) |
| | ZK1067.2 | NFX1-type zinc finger-containing protein 1 homolog; Epigenetic inheritance factor which, in association with the Argonaute protein wago-4, mediates small RNA-directed transgenerational epigenetic inheritance and thus balances the transgenerational inheritance of epigenetic information. Specifically, maintains a balanced production of small RNAs by preventing the spread of epigenetic signals towards the 5'-end of target mRNAs. Plays a role in small RNA- induced gene silencing in the germline. (2443 aa) |
| | sym-2 | RNA-binding protein sym-2; mRNA splicing factor that regulates alternative splicing of many genes in embryo. Probably plays a role in the formation of embryo- specific isoforms; Belongs to the ESRP family. (618 aa) |
| | nos-2 | Nanos-type domain-containing protein; Belongs to the nanos family. (259 aa) |
| | sor-1 | Sop-2-related protein 1; Acts synergistically with sop-2 to maintain the transcriptionally repressive state of homeotic genes throughout development. Not required to initiate repression, but to maintain it during later stages of development. Also required to repress expression of other genes. Binds RNA in a sequence-independent manner. (1000 aa) |
| | npp-10 | Nuclear pore complex protein Nup98-Nup96; Nup98 and Nup96 play a role in the bidirectional transport across the nucleoporin complex (NPC). Required for the nuclear import of hcp-4 during mitotic prophase, this step is essential for centrosome assembly and resolution. Regulates nucleoporin npp-5 localization to the nuclear membrane during interphase and to kinetochores during metaphase. Has a role in P granule integrity; may promote the 'liquid phase' of P granules by increasing the number of interacting RNA-protein complexes. Binds nos-2 mRNA, probably indirectly, and promotes its accu [...] (1678 aa) |
| | pgl-1 | Guanyl-specific ribonuclease pgl-1; Guanyl-specific endoribonuclease which cleaves the phosphodiester bond in single-stranded RNA between the 3'-guanylic residue and the 5'-OH residue of adjacent nucleotide, resulting in the formation of a corresponding 2',3'-cyclic phosphate intermediate. Together with the P-granule component pgl-3, is involved in the formation of P-granules. Together with pgl-3, probably recruits other granule components such as pos-1, mex-3 and glh-1 to P-granules. In addition, may act redundantly with pgl-3 to protect germ cells from excessive germline apoptosis du [...] (771 aa) |
| | ZK512.2 | Probable ATP-dependent RNA helicase DDX55 homolog; Probable ATP-binding RNA helicase. (578 aa) |
| | ZK512.4 | Signal recognition particle 9 kDa protein; Signal-recognition-particle assembly has a crucial role in targeting secretory proteins to the rough endoplasmic reticulum membrane. SRP9 together with SRP14 and the Alu portion of the SRP RNA, constitutes the elongation arrest domain of SRP. The complex of SRP9 and SRP14 is required for SRP RNA binding (By similarity). (76 aa) |
| | ZK616.1 | Uncharacterized protein. (251 aa) |

| | ZK686.2 | Putative ATP-dependent RNA helicase ZK686.2; Probable ATP-binding RNA helicase; Belongs to the DEAD box helicase family. (593 aa) |
| | ZK856.11 | Probable RNA-binding protein EIF1AD; Belongs to the EIF1AD family. (175 aa) |
| | elpc-3 | Elongator complex protein 3; Catalytic tRNA acetyltransferase subunit of the RNA polymerase II elongator complex, which is a component of the RNA polymerase II (Pol II) holoenzyme and is involved in transcriptional elongation. The elongator complex is required for multiple tRNA modifications, including mcm5U (5-methoxycarbonylmethyl uridine), mcm5s2U (5-methoxycarbonylmethyl-2-thiouridine), and ncm5U (5- carbamoylmethyl uridine) (By similarity). In the elongator complex, acts as a tRNA uridine(34) acetyltransferase by mediating formation of carboxymethyluridine in the wobble base at po [...] (547 aa) |
