What's a GeneRIF?

The C. elegans NudE homolog NUD-2 is dispensable for dynein- and LIS-1-dependent mitotic spindle assembly in the zygote. This facilitates functional characterization of kinetochore-localized NUD-2, which is recruited by the CENP-F-like proteins HCP-1 and HCP-2 independently of RZZ-Spindly and dynein-LIS-1.
Title: NudE regulates dynein at kinetochores but is dispensable for other dynein functions in the C. elegans early embryo.
show that HCP-1 and HCP-2 recently implicated in the spindle assembly checkpoint (SAC) function, do not have identical functions, since hcp-1(RNAi), but not hcp-2(RNAi), enhances the lethality of the spindle assembly checkpoint components mutants
Title: Synthetic lethal interactions identify phenotypic "interologs" of the spindle assembly checkpoint components.
The key role of HCP-1/2 is to target CLASP(CLS-2) to kinetochores to mediate chromosome segregation.
