What's a GeneRIF?

the model organism yeast the lipid droplet associated GPAT Gpt2 requires phosphorylation at a conserved motif to prevent a futile triacylglycerol cycle.
Title: Phosphorylation of the lipid droplet localized glycerol‑3‑phosphate acyltransferase Gpt2 prevents a futile triacylglycerol cycle in yeast.
results argue that motifs I, II and III of Gpt2p are in the lumen of the endoplasmic reticulum (ER) and support the notion that the active site of Gpt2p resides in the ER lumen
Title: Topology of the microsomal glycerol-3-phosphate acyltransferase Gpt2p/Gat1p of Saccharomyces cerevisiae.
Gat1 and Gat2 localized to both perinuclear and cortical endoplasmic reticula in actively proliferating cells.
Title: Glycerol-3-phosphate acyltransferases gat1p and gat2p are microsomal phosphoproteins with differential contributions to polarized cell growth.
