GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. Regulation of sucrose-phosphate synthase by BSK8 occurs through activation of a phosphatase that in turn may dephosphorylate sucrose-phosphate synthase and thus activates the enzyme.
    Title: A kinase-phosphatase signaling module with BSK8 and BSL2 involved in regulation of sucrose-phosphate synthase.
  2. SPSA1 plays a role in photosynthetic sucrose synthesis in Arabidopsis leaves. Decreases in leaf SPS activity lead to increased starch synthesis and turnover, and decreased RuBP regeneration-limited photosynthesis but not Rubisco-limited photosynthesis.
    Title: Decrease in leaf sucrose synthesis leads to increased leaf starch turnover and decreased RuBP regeneration-limited photosynthesis but not Rubisco-limited photosynthesis in Arabidopsis null mutants of SPSA1.
