Protein
Type 2A phosphatase-associated protein 42
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Involved in negative regulation of the TOR signaling pathway in response to type of available nitrogen source. Inhibitor of PP2A phosphatase SIT4, which results in inhibition of nuclear export of MSN2, due to lack of dephosphorylation by SIT4. Also required for rapamycin induced activation of expression of many nitrogen discrimination pathway (NDP) genes. In complex with PPH21, required for organization of the actin cytoskeletom during the cell cycle via a Rho GTPase-dependent mechanism.
Similarity
Belongs to the IGBP1/TAP42 family.
