Target Background

Function
E3 ubiquitin-protein ligase involved in the regulation of protein import in the chloroplast. Associates with TOC complexes and mediates ubiquitination of TOC components, promoting their degradation via the ubiquitin-proteasome system (UPS). Plays a role in the reorganization of the TOC machinery. Involved in a mechanism that regulates plastid biogenesis via UPS. Promotes stress tolerance by depleting the chloroplast protein import apparatus, which limits photosystem assembly and the potential for reactive oxygen species (ROS) formation. May act as negative regulator of programmed cell death (PCD) during biotic stress.
Gene References into Functions
  1. In this study, we identified the Arabidopsis RING-type E3 ubiquitin ligase SP1 as a peroxisome membrane protein that regulates peroxisome biogenesis. PMID: 27799549
  2. SP1 protein (At1g63900) associated with TOC (translocon at the outer envelope of chloroplasts) complexes and mediated ubiquitination of TOC components, promoting degradation; mutant sp1 plants performed developmental transitions involving plastid proteome changes inefficiently, indicating requirement for reorganization of TOC machinery PMID: 23118188
Subcellular Location
Plastid, chloroplast outer membrane; Multi-pass membrane protein.
