Abstract

This entry represents a group of putative E3 ubiquitin-protein ligases, including SPL2 from Arabidopsis. SPL2 shares topological similarity and considerable sequence identity with SP1, and is located in the chloroplast envelope [ 1 ]. SP1 is associated with TOC (translocon at the outer envelope of chloroplasts) complexes and mediates ubiquitination of TOC components, promoting their degradation [ 2 ].
