Graduate Scholarships available – 2023 entry: The Newstead group currently has a graduate Scholarship available for entry in 2023. The MRC enterprise scholarship, in collaboration with OMass therapeutics, seeks to decipher the lipid code using native mass spectrometry and structural biology for amino acid transporters in the cell. Closing date – December 9th.
August 22nd 2022: Dysregulation of lysosomal membrane proteins play major roles in metabolic diseases. To advance our understanding of lysosomal biology we recently published the crystal structure and functional characterisation of cystinosin (CTNS) in Nature Communications. Cystinosin is responsible for recycling cyteine in the cell, and mutations in the gene encoding CTNS cause Cystinosis, a lysosomal storage disorder. Our latest work will drive new direction in our efforts to understand the causes of lysosome dysfunction and develop new insights into cell homeostasis and human disease treatment.
December 8th 2021: The molecular basis for cystine/glutamate exchange across the plasma membrane is now out in Nature Communications! System xc- (SLC7A11) is a key regulator of cellular redox levels and a major target for novel anticancer drugs and new tools to understand Feroptosis, a recently described cell death pathway resulting from lipid peroxidation.
March 3rd 2022: Also see our related paper in Molecular Cell, implicating SLC7A11 in kynurenine transport and anti-ferroptotic signalling.
September 26th 2021: PepT1 and PepT2 are responsible for the absorption and retention of dietary peptides and beta-lactam antibiotics in the small intestine and kindey respectively. Here we report the cryo-EM structure of the renal peptide transporter, PepT2, and reveal an accurate ligand binding template for drug development. Read our results here in Sci Adv.
