PP4/PPP4C Antibody (501517)

The catalytic subunit of Protein Phosphatase 4 (PP4), also called PPX, is a serine/threonine protein phosphatase with about 65% homology to PP2A. Although PP4 has the same heterotrimeric subunit structure as PP2A and can use many of the PP2A regulatory subunits, PP4 also has its own unique scaffolding and regulatory subunits. PP4 is largely found in the centrosome of the nucleus where it may play a role in modulating transcription factor phosphorylation by JNK. In Drosophila, cmm mutants have low levels of PP4 and are unable to complete mitosis due to a deficit in microtubule assembly.
