What is janus kinases (JAKs)?

When a signal binds to the Tyrosine kinase receptor (RTK), you have studied that a list of events occur sequentially. Map the events in the correct order from 1st to the last step.

What happens if a kinase is overactive and phosporylates the protein too much?

please answer 15,16,17

Nerve growth factor binds to which type of receptor? a.) Receptor tyrosine phosphatases b.) Receptor Serine/Threonine Kinase c.) Receptor guanylyl cyclase d.) Receptor tyrosine kinase

Which of the following statements is false?   Question 11 options:   a)  Nucleotides and amino acids can act as extracellular signal molecules.   b)  Some signal molecules can bind directly to intracellular proteins that bind DNA and regulate gene transcription.   c)  Some signal molecules are transmembrane proteins.   d)  Dissolved gases such as nitric oxide (NO) can act as signal molecules, but because they cannot interact with proteins they must act by affecting membrane lipids.

This inhibatory kinase phosphorylates an inactive M-Cdk. a) M-kinase b) Wee1 c) CAK d) Cdc25

What is the largest family of cell surface receptors (>1% of the human genome)?
