Dynein light chain (DLC-1) is a light chain component of the dynein motor complex, it functions as an allosteric regulator of multi-subunit protein complexes and promotes P granule integrity in the C. elegans embryo. P granules are RNA-protein complexes located in the C. elegans germline that are important for RNA regulation and fertility. To further study the role of DLC-1 during C. elegans embryogenesis we performed quantitative tandem mass tag mass spectrometry on embryos after
dlc-1 knock down. The amount of core P granule components and nucleoporin proteins did not change after
dlc-1(RNAi). These results show that DLC-1 does not help regulate P granule protein levels and support the model that DLC-1 facilitates phase separation of P granule components in vivo .
