tyrosine phosphatases

Tyrosine phosphatases are enzymes that regulate cell functions by removing phosphate groups from specific proteins called tyrosine residues. This process, known as dephosphorylation, helps control signaling pathways involved in cell growth, differentiation, and communication. By turning off or modulating signals, tyrosine phosphatases maintain balanced cellular activity and prevent abnormal growth, such as cancer. They work in concert with tyrosine kinases, which add phosphate groups, ensuring precise control over cell responses to various stimuli. Overall, tyrosine phosphatases are essential for maintaining normal cell function and signaling regulation.
