This entry represents the E3 ubiquitin-protein ligase SINA-like proteins from plants, including SINL1-10 (except SINL5) from Arabidopsis. Seven in absentia (SINA) proteins are E3 ligases containing an N-terminally located RING finger domain, followed by the conserved SINA domain that is involved in substrate binding and dimerization. Plant SINA-like proteins are putative E3 ubiquitin ligases [ 1 ].
