Protein: Seipin-2 (AtSEIPIN2) (F4I340)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Involved in lipid metabolism and lipid droplet (LD) morphology, number, and size. Supports the formation of small-sized LDs and modulates triacylglycerol accumulation. Induces probably a reorganization of the endoplasmic reticulum into LD-forming domains.
Subcellular location: Endoplasmic reticulum membrane {ECO:0000269|PubMed:26362606}; Multi-pass membrane protein {ECO:0000255}. Note=Localized to the lipid droplet-forming sites. {ECO:0000269|PubMed:26362606}.
InterPro domains:
- IPR009617: Seipin family (family) [98-521]
