NCIt definition : A transmembrane protein expressed on the surface of target cells that is specific
for binding insulin-like growth factor (IGF) proteins. There are two IGF receptors,
one of which has receptor tyrosine kinase activity similar to insulin receptor (INSR).;
Alternative definition : NCI-GLOSS: A protein found on the surface of some types of cells that binds to insulin-like
growth factor (IGF). This causes the cells to grow and divide. Insulin-like growth
factor receptor is found at high levels on the surface of several types of cancer
cells, which causes these cells to grow rapidly in the presence of IGF.;
