A Chicken Tapasin ortholog can chaperone empty HLA molecules independently of other peptide-loading components

Posted by klaurent Rockefeller

Kavli Affiliate: Michael W. Young | Authors: Georgia F Papadaki, Claire H Woodward, Michael C Young, Trenton J Winters, George M Burslem and Nikolaos G Sgourakis | Summary: Human Tapasin (hTapasin) is the main chaperone of MHC-I molecules, enabling peptide loading and antigen repertoire optimization across HLA allotypes. However, it is restricted to the endoplasmic […]

Kavli Affiliate: Ali H. Brivanlou | Authors: Tiago L Laundos, Shu Li, Eric Cheang, Riccardo De Santis, Francesco M Piccolo and Ali H. Brivanlou | Summary: Huntington’s disease (HD) remains an incurable and fatal neurodegenerative disease long after CAG-expansion mutation in the huntingtin gene (HTT) was identified as the cause. The underlying pathological mechanism, whether […]
