The event lasted for three days. iHuman hosted its 8th iHuman Forum from October 18 to 20 in the Conference Center. The Forum aims to be a platform for researchers to present and exchange their latest advances in the fields of structural biology, chemical biology, computational biology, medicinal chemistry and cryo-electron tomography. The opening of the forum was presided over by Raymond Stevens,...

The taste sensory system is responsible for examining food nutrition and avoiding ingestion of harmful substances. In humans, the tastants evoke five distinct taste sensations: sweet, bitter, salty, sour and umami. Interestingly, ion channels transduce the sour and salty signals, whereas, sweet, umami and bitter taste are mediated by G protein-coupled receptors (GPCRs). Among the five ta...

According to the 2019 World Health Organization (WHO) report, over 350 million people worldwide live with depression, with an annual increase rate of approximately 18%. In China, depression affects over 95 million people. About 67% of those with depression had suicidal ideation, and 25% attempted suicide. However, most existing antidepressants are slow-acting, short-enduring and have low response ...

  The voltage-gated potassium (Kv) channels promote the outflow of potassium ions in the repolarization phase of the action potential and play a crucial role in regulating the membrane potential of excitable cells in the neuronal and cardiovascular systems. The human Kv channels are composed of 12 subfamilies (Kv1-Kv12), among which Kv7, also known as KCNQ channe...

The research group led by Prof. Xu Fei at iHuman Institute o recently reported a new structure of the Frizzled receptors - an emerging class of cancer targets. They determined the first G-protein complexed Frizzled receptor structure and published their findings in the high-impact journal - Cell Research, with the title “Cryo-EM structure of constitutively active human Frizzled 7 in complex ...

Recently, Dr. Zhao Suwen’s team at the iHuman Institute, collaborating with other scientists from Tianjin University, and the Agency for Science, Technology and Research (A*STAR)/ University of Illinois at Urbana-Champaign (UIUC) have solved a long-standing mystery of Z genome that comprises entirely non-canonical Z-T base pairs instead of canonical A-T base pairs in bacteriophages (Figure 1). Th...

iHuman Institute Distinguished Professor Dr. Kurt Hermann Wüthrich, Nobel  Laureate in Chemistry, was honored with the 2020 Magnolia Award in recognition of his great contributions and achievements in scientific research, and for nurturing and mentoring Chinese young scientists.The Magnolia Award, which has been awarded annually since 1989, was established to commend...

A research team from iHuman Institute of ShanghaiTech University has made a new discovery in the field of human chemokine system. This study fills in a critical gap, which is how endogenous chemokines activate endogenous chemokine receptors. The article, entitled Structure basis of CXC chemokine receptor 2 activation and signaling was published in the prestigious journal Nature, available onl...

Researchers at the iHuman Institute of ShanghaiTech University have made another discovery in the advancement of human health, this time involving an important protein for controlling obesity - the melanocortin-4 receptor. The research is to be published in the prestigious journal Science, available online from April 24, 2020. The Stevens lab which led the work has been intensely focused...

Researchers from the iHuman Institute at ShanghaiTech University, Chinese Academy of Sciences (Shanghai Institute of Materia Medica, SIMM), East China Normal University, University of Southern California, and the Danish biopharmaceutical company, Novo Nordisk, have determined the first “peptide-free inactive structure of the full-length human glucagon like peptide-1 receptor (GLP-1R) at atomic re...

Recently, Prof. Shui Wenqing’s group from iHuman Institute and SLST has made a breakthrough in bioactive screening from herbal extracts. Based on their previous work in developing the affinity mass spectrometry (MS) technique for ligand screening (Chemical Science 2018, Analytical Chemistry 2019), they combined affinity MS-based screening with compound isolation and ...

Recently, scientists from Xu Fei's lab at iHuman Institute, ShanghaiTech University with their collaborators made a new breakthrough in the field of human cell signaling research. They successfully resolved the 3D protein structures of the first human orphan GPR52 receptor and presented a full structural landscape covering the receptor’s different functional states: ligand-free state, ligand-...

A team of scientists led by Professors Liu Zhi-Jie and Hua Tian at the iHuman Institute of ShanghaiTech University has determined and analyzed the high-resolution atomic structures of human cannabinoid receptors, also known as the “marijuana receptors”, 1 and 2 (CB1 and CB2) complexed with their agonists and downstream signaling G proteins. The results, described in a paper entitl...

iHuman Institute Professor Raymond C. Stevens and his team recently elucidated the first crystal structures of the δ-opioid receptor (DOP) in an activated state. The results were published in the journal Science Advances, in an article titled “Elucidating the active δ-opioid receptor crystal structure with peptide and small-molecule agonists.” ShanghaiTech University PhD student Yu Jing from R...
