STD1

MSN3, SFS3, L000002111, YOR047C
Protein involved in control of glucose-regulated gene expression; interacts with kinase Snf1p, glucose sensors Snf3p and Rgt2p, TATA-binding Spt15p; regulator of transcription factor Rgt1p; interactions with Pma1p appear to propagate [GAR+]; STD1 has a paralog, MTH1, that arose from the whole genome duplication

SNF1

CAT1, CCR1, GLC2, HAF3, PAS14, AMP-activated serine/threonine-protein kinase catalytic subunit SNF1, L000001944, YDR477W
AMP-activated serine/threonine protein kinase; found in a complex containing Snf4p and members of the Sip1p/Sip2p/Gal83p family; required for transcription of glucose-repressed genes, thermotolerance, sporulation, and peroxisome biogenesis; involved in regulation of the nucleocytoplasmic shuttling of Hxk2p; regulates filamentous growth in response to starvation; SUMOylation by Mms21p inhibits its function and targets Snf1p for destruction via the Slx5-Slx8 Ubiquitin ligase
Saccharomyces cerevisiae (S288c)

Two-hybrid

Bait protein expressed as a DNA binding domain (DBD) fusion and prey expressed as a transcriptional activation domain (TAD) fusion and interaction measured by reporter gene activation.

Std1p (Msn3p) positively regulates the Snf1 kinase in Saccharomyces cerevisiae.

Kuchin S, Vyas VK, Kanter E, Hong SP, Carlson M

The Snf1 protein kinase of the glucose signaling pathway in Saccharomyces cerevisiae is regulated by an autoinhibitory interaction between the regulatory and catalytic domains of Snf1p. Transitions between the autoinhibited and active states are controlled by an upstream kinase and the Reg1p-Glc7p protein phosphatase 1. Previous studies suggested that Snf1 kinase activity is also modulated by Std1p (Msn3p), which interacts ... [more]
