According to recent research from the United States, "The calcium-activated protein phosphatase calcineurin is controlled by regulator of calcineurin (RCAN) in organisms ranging from yeast to mammals. Here we performed a yeast two-hybrid screen with RCAN1 as bait, identifying TAK1 binding protein 2 (TAB2) as an interacting partner."

"TAB2 interacted directly with RCAN1 in vitro and in vivo, recruiting TAK1, TAB1 and calcineurin, forming a macromolecular signalling complex. Overexpression of TAK1 and TAB1, or active TAK1(Delta N), promoted direct phosphorylation of RCAN1 in vitro and in vivo. TAK1 phosphorylated RCAN1 at Ser 94 and Ser 136, converting RCAN1 from an...
