Some human diseases cause a malfunction in protein phosphatases. describe a protein phosphatase and its role in cell signaling, and then explain how a malfunction in this type of protein would affect signaling pathways.

Protein phosphates have the opposite effect as protein kinases. They dephosphorylate proteins. An example is the  Protein phosphatase 1 that is significant to transcription regulation in the cell nucleus.  If Protein phosphatases are not working, the cells would be unable to respond to environmental stimuli and would die.
