What's a GeneRIF?

study identified a RhoGAP, PAC-1, which mediates embryo radial polarity & gastrulation by excluding PAR-6 from contacted cell surfaces; PAC-1 provides a dynamic molecular link between cell contacts & PAR proteins that polarizes embryos radially
Title: Polarization of the C. elegans embryo by RhoGAP-mediated exclusion of PAR-6 from cell contacts.
