    Summary
    Enables phosphoprotein phosphatase activity. Involved in several processes, including cellular response to amino acid starvation; negative regulation of TORC1 signaling; and positive regulation of transcription by RNA polymerase II. Located in plasma membrane. Orthologous to several human genes including CTDSP2 (CTD small phosphatase 2). [provided by Alliance of Genome Resources, Dec 2024]

    • Plasma membrane-associated protein phosphatase; involved in the general stress response and the inactivating dephosphorylation of Mep2p; required along with binding partner Whi2p for full activation of STRE-mediated gene expression, possibly through Msn2p dephosphorylation, and for inhibition of TORC1 in response to limiting amino acids; regulates the sodium ion stress response with Psr2p; member of the HAD family of protein phosphatases
