CC -!- FUNCTION: Together with SLM2, effector of the TORC2- and calcineurin-
CC signaling pathways. Phosphorylated and activated by TORC2 under
CC favorable growth conditions. Mediates actin polarization via inhibition
CC of calcineurin-dependent transcription. Upon nutrient limitation or
CC environmental stress, gets dephosphorylated by calcineurin.
CC Dephosphorylation inhibits its interaction with TORC2, thereby
CC antagonizing TORC2 signaling and mediating calcineurin-dependent actin
CC depolarization. Also functions in heat-induced, calcineurin-mediated
CC uracil permease (FUR4) endocytosis. {ECO:0000269|PubMed:15372071,

CC ECO:0000269|PubMed:16959779}.
CC -!- SUBUNIT: Heterodimer of SLM1-SLM2. Binds phosphatidylinositol 4,5-
CC bisphosphate, which is required for function. Interacts with the TORC2
CC subunits AVO2, BIT61 and TOR2. Interacts with the calcineurin catalytic
CC subunits CNA1 and CNA2. {ECO:0000269|PubMed:15372071,

CC ECO:0000269|PubMed:15689497}. Note=Localizes to cortical punctate
CC structures. Correct localization requires phosphatidylinositol 4,5-
CC bisphosphate and functional TORC2.
CC -!- PTM: Phosphorylated by the target of rapamycin complex 2 (TORC2) and
CC dephosphorylated by serine/threonine-protein phosphatase 2B
CC (calcineurin). {ECO:0000269|PubMed:15372071}.
CC -!- MISCELLANEOUS: Present with 5190 molecules/cell in log phase SD medium.
