ID Q9UU91; PN Protein yop1; GN yop1; OS 284812; SL Nucleus Position: SL-0178; SL Nucleus Position: SL-0182; SL Comments: Endoplasmic reticulum membrane {ECO:0000269|PubMed:20434336}; Multi-pass membrane protein {ECO:0000269|PubMed:20434336}. Nucleus membrane {ECO:0000269|PubMed:20434336}; Multi-pass membrane protein {ECO:0000269|PubMed:20434336}. Note=Enriched at the cell equator during mitosis. DR UNIPROT: Q9UU91; DR Pfam: PF03134; DE Function: Required to generate and maintain the structure of the tubular endoplasmic reticulum network and the vacuole. Induces high curvature in membranes and causes membrane tubule formation. Involved in membrane/vesicle trafficking (By similarity). Required for the correct positioning of the cellular division plane by delimiting the actomyosin ring assembly at the cell equator (PubMed:20434336). {ECO:0000250|UniProtKB:Q12402, ECO:0000269|PubMed:20434336}.
