Snf1 and AMPK pathways. Analogy between budding yeast's Snf1 and mammalian AMPK pathways is illustrated. Elm1/Sak1/Tos3 redundantly activates Snf1 which is involved in metabolic control and stress response. LKB1/CaMKK/TAK1 activates AMPK which is implicated in metabolic control, stress response, cell division cycle and cell polarity. Kin4 is activated by Elm1 and mediates coordination of mitotic exit with spindle alignment along the polarity axis. Elm1 is also involved in regulation of other proteins related with polarity and cell division. Solid lines indicate direct activation of the protein catalytic activity. Dashed lines represent involvement of the indicated proteins in the regulation of the corresponding proteins or pathways directly or indirectly.
