NCIt definition : Insulin receptor-related protein (1297 aa, 144 kDa) is encoded by the human INSRR
gene. This protein plays a role in pH-mediated signaling;
NCIt note : Insulin receptor-related protein is cleaved to form an alpha and a beta subunit. The
mature receptor is a tetramer of 2 alpha and 2 beta chains linked by disulfide bonds.
The alpha chains form the ligand-binding domain, while the beta chains exhibit kinase
activity. (UniProt);
