Crystal structure of the LOTUS domain (aa 139-222) of Drosophila Oskar in C222Crystal structure of the LOTUS domain (aa 139-222) of Drosophila Oskar in C222
Structural highlights
Function[OSKA_DROME] Organizes the germ plasm and directs localization of the posterior determinant nanos. Oskar protein is required to keep nos RNA and staufen protein at the posterior pole.[1] [2] [3] Publication Abstract from PubMedIn many animals, the germ plasm segregates germline from soma during early development. Oskar protein is known for its ability to induce germ plasm formation and germ cells in Drosophila. However, the molecular basis of germ plasm formation remains unclear. Here, we show that Oskar is an RNA-binding protein in vivo, crosslinking to nanos, polar granule component, and germ cell-less mRNAs, each of which has a role in germline formation. Furthermore, we present high-resolution crystal structures of the two Oskar domains. RNA-binding maps in vitro to the C-terminal domain, which shows structural similarity to SGNH hydrolases. The highly conserved N-terminal LOTUS domain forms dimers and mediates Oskar interaction with the germline-specific RNA helicase Vasa in vitro. Our findings suggest a dual function of Oskar in RNA and Vasa binding, providing molecular clues to its germ plasm function.
