PPP3R2 is a calcium-dependent, calmodulin stimulated serine/threonine protein phosphatase. In eukaryotes, the phosphorylation and dephosphorylation of proteins on serine and threonine residues is an essential means of regulating a broad range of cellular functions including division, homeostasis and apoptosis. In general, the protein phosphatase (PP) holoenzyme is a trimeric complex composed of a regulatory subunit, a variable subunit and a catalytic subunit.
Source:Recombinant corresponding to aa1-173 from human PPP3R2 fused to His-tag at N-terminus, expressed in E.coli.
Molecular Weight:~22kD (193aa), confirmed by MALDI-TOF
Enzyme Activity:Not determined. This product is recommended for use in applications that do not require a catalytically active form of the protein.
