Product Specific Information
This antibody detects endogenous levels of MKP1/2 only when phosphorylated at Serine 296/318.
Target Information
Mitogen-activated protein kinase phosphatases (MKPs) are 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, is expressed in various tissues, and localized in the nucleus.
Transcription factor E2F-1 regulates MKP2 expression, and the E2F-1/MKP2 pathway mediates apoptosis under oxidative stress.
MKP2 also acts as a transcriptional target of p53, mediating apoptosis via a 10-bp palindrome motif (CTGGCGCCAG) in the MKP2 promoter.
