Angiotensin-converting enzyme 2 (ACE2) is the cellular receptor for SARS coronavirus (SARS-CoV) and the new coronavirus (SARS-CoV-2) that is causing the serious epidemic COVID-19. Here we present cryo-EM structures of full-length human ACE2, in the presence of a neutral amino acid transporter B0AT1, with or without the receptor binding domain…[Read more]

In case of EpCAM, increased membranous expression of EpCAM was associated with nucleolar grade and tumor necrosis in ccRCC. Additionally, membranous EpCAM expression added prognostic value in patients with ccRCC who had high nucleolar grade versus low nucleolar grade. Moreover, membranous EpCAM expression was found to be an independent favorable…[Read more]
