Expression Pattern :

Pattern  Immunoreactive PLP-1 localizes to the nuclei of all blastomeres beginning by the two-cell stage of embryogenesis, implying that PLP-1 is a maternally encoded transcription factor. It is also present in the germline-specific P granules of early embryos. Primary Identifier  Expr8706
Remark  Picture: Fig. 5. The same pattern was seen with two separate antibodies raised against distinct PLP-1 peptides, and both nuclear and P granule expression was largely eliminated in plp-1 (RNAi) embryos, confirming their specificity. Subcellular Localization  PLP-1 is transiently asymmetrically localized during telophase of the dividing EMS cell (observed in 12 embryos at the correct stage), with higher levels of the protein in the chromatin of the future E cell nucleus and low or undetectable levels in that of MS. A similar transient asymmetry in PLP-1 levels was observed at many divisions throughout early development, starting at cleavage of the zygote, with higher levels seen in the cytoplasm and forming nucleus of the posterior daughter, P1 (observed in 5 embryos). The anteroposterior asymmetry in PLP-1 was also observed in the AB lineage during the division of the AB granddaughters (observed in 7 embryos): for example, PLP-1 is higher in the chromatin of the posterior daughter ABalp than that of its anterior sister ABala. In all cases, the asymmetry was observed only during telophase and at the time that nuclei were reassembling after cell division; the staining was symmetric at all other times. PLP-1 was always seen at higher levels in the forming nuclei of the posterior daughters.
