Select statements that accurately describe receptor tyrosine kinases (RTKs). Some RTKs are dimeric in the presence of a ligand. GTPase activity is required for autophosphorylation (cross-phosphorylation). The structure includes a transmembrane helix. The intracellular domain has kinase domains.
Figure 9.8 HER2 is a receptor tyrosine kinase. In 30 percent
In 30 percent of human breast cancers, HER2 is permanently activated, resulting in unregulated cell division. Lapatinib, a drug used to treat breast cancer, inhibits HER2 receptor tyrosine kinase autophosphorylation (the process by which the receptor adds phosphates onto itself), thus reducing tumor growth by 50 percent.
