There are ten mitogen-activated protein kinase (MAPK) phosphatases (MKPs) that act as negative regulators of MAPK activity in mammalian cells. MKP2 (DUSP4) is a dual threonine/tyrosine phosphatase that specifically dephosphorylates and inactivates MAPKs (ERK, JNK, p38). It contains one Rhodanese domain and one tyrosine-protein phosphatase domain. MKP2 is expressed in a variety of tissues, and is localized in the nucleus. Transcription factor E2F-1 acts as a transcriptional regulator of MKP2. E2F-1/MKP2 pathway mediates apoptosis under oxidative stress and that MKP2 suppresses tumor formation. MKP2 is a novel transcription target of p53 in mediating apoptosis by 10-bp palindrome motif (CTGGCGCCAG) in the MKP2 promoter.
