Professor Arieh Katz PhD

Receptor Biology Group

Arieh Katz

Division of Chemical & Systems Biology, Department of Integrative Biomedical Sciences, Faculty of Health Sciences, UCT

The Group's mission is to study the structure and function of G protein-coupled receptors and to apply the research to understanding and treating diseases that have major effects on the social and economic welfare of South Africa.

The G protein-coupled receptors (GPCRs) constitute the largest family of membrane proteins in the human genome (>80%) and they are the targets of about 50% of therapeutics. Despite this, only 10% of GPCRs in the human genome have been exploited for drug development and they thus remain a rich source for tackling human disease.  GPCR therapeutics target a wide range of disease, including reproductive, endocrine, cardiac, inflammatory and psychiatric disorders, as well as pain and obesity. GPCRs also have important roles in cancer and infectious disease, especially HIV/AIDS.

The research of the Group is organized into two themes:

  1. GPCRs in the Health and Dysfunction of the Reproductive System
  1. GPCRs in sexually-transmitted infections

Each theme consists of several research programmes that focus on a specific GPCR and its role in human disease or disorder.
