A team of scientists has answered a long-standing question in cell biology , uncovering h ow the cell's main energy currency, ATP , is transported into the endoplasmic reticulum ( ER ) . Disrupted energy transport could affect diseases such as type 2 diabetes, cancer, and neurodegenerative disorders . The study, " Step-wise ATP translocation into the ER by human SLC35B1 " published in Nature , confirms that the transporter protein SLC35B1 is the key gateway for ATP entry into the ER . The research , led by David Drew, professor of biochemistry at Stockholm University and located at SciLifeLab , reveals the first structural and mechanistic insight into how ATP enters the endoplasmic reticulum (ER) using the transporter protein SL...
