Description of YPL203W: Subunit of cytoplasmic cAMP-dependent protein kinase, which contains redundant catalytic subunits Tpk1p, Tpk2p, and Tpk3p and regulatory subunit Bcy1p; promotes vegetative growth in response to nutrients; activates filamentous growth[1][2][3][4]

Genetic interaction with ATF1
Mutation type(s): deletion/partial inactivating

ATF1 is transcriptionally induced by glucose and sucrose. This regulation depends on Ras/cAMP/PKA signaling. Long-term expression of ATF1 requires both a fermentable carbon source and a nitrogen source. This regulation depends on FGM signaling. [5] [6]
