| | | Concise_description | par-2 encodes a protein containing a C3HC4-type RING-finger, a specialized type of zinc-finger found in E3 ubiquitin ligase subunits; PAR-2 is required maternally for polarization of the C. elegans zygote along the anterior-posterior (A-P) axis and is asymmetrically localized to the posterior cortex of the one- and two-cell embryo via interdependent interactions with PAR-3, PAR-6, and PKC-3. |
