S.cerevisiae - Yeastract

Gene Ontology Information

Protein Name	Gpb2p
Description	Multistep regulator of cAMP-PKA signaling; inhibits PKA downstream of Gpa2p and Cyr1p, thereby increasing cAMP dependency; inhibits Ras activity through direct interactions with Ira1p/2p; regulated by G-alpha protein Gpa2p; GPB2 has a paralog, GPB1, that arose from the whole genome duplication
GO Terms: Biological Process	level 3: signal transduction level 4: pseudohyphal growth level 4: ascospore formation level 7: regulation of cell shape level 7: glucose mediated signaling pathway level 7: invasive growth in response to glucose limitation level 9: negative regulation of Ras protein signal transduction level 10: negative regulation of cAMP-dependent protein kinase activity
GO Terms: Molecular Function	level 4: GTPase activating protein binding level 7: cAMP-dependent protein kinase inhibitor activity
GO Terms: Cellular Component	level 3: cytoplasm level 4: mitochondrion level 4: plasma membrane level 5: cell cortex of cell tip
