What's a GeneRIF?

Zyg9, the XMAP215/Dis1 homolog in C. elegans exhibits a polymerase activity which is built by combining multiple tubulin-binding TOG domains and a basic lattice-binding region.
Title: XMAP215 polymerase activity is built by combining multiple tubulin-binding TOG domains and a basic lattice-binding region.
These findings indicate that ZYG-9-TAC-1 and ZYG-8 act in a partially redundant manner to ensure correct microtubule assembly throughout the cell cycle of early C. elegans embryos.
Title: ZYG-9, TAC-1 and ZYG-8 together ensure correct microtubule function throughout the cell cycle of C. elegans embryos.
Positioning of the germinal vesicle is dependent on zyg-9.
Title: MEI-1/katanin is required for translocation of the meiosis I spindle to the oocyte cortex in C elegans.
ZYG-9 and TAC-1 physically interact in vivo, and this interaction is important for the efficient localization of the ZYG-9/TAC-1 complex to centrosomes
Title: Caenorhabditis elegans TAC-1 and ZYG-9 form a complex that is essential for long astral and spindle microtubules.
mutual stabilization between TACC and Zyg-9 proteins is a key feature ensuring microtubule assembly in vivo
Title: TAC-1 and ZYG-9 form a complex that promotes microtubule assembly in C. elegans embryos.
