Question

what's the answer?

Question 2 1 pts USE THIS INFORMATION FOR ALL QUESTIONS: Many forms of cancer are influenced by hormones and growth factors. Some breast cancers are "HR-positive" or "HR-negative and "HER2-positive" or "HER2-negative," meaning that the tumor cells have or lack hormone receptors (HR) for estrogen and/or progesterone, and they have or lack receptors (called HER2) for human epidermal growth factor 2 (EGF-2). The HER2 has intrinsic (built-in) tyrosine kinase activity. Based on this, what can you infer about hEGF2 or the HER2 receptor? hEGF2 is a steroid. hEGF2 is hydrophobic. The HER2 receptor is capable of phosphorylating proteins, The HER2 receptor regulates sodium channels. The HER2 receptor is nonfunctional. Next

Answer 1

The HER2 receptor is capable of phosphorylating proteins.

A tyrosine kinase is an enzyme that can transfer a phosphate group from ATP to a protein in a cell. It functions as an "on" or "off" switch in many cellular functions, thereby phosphorylating many enzymes activating or deactivating them.
