High impact information on SUC1


Biological context of SUC1

  • The SUC1/CKS1 proteins interact with cyclin-dependent kinases (CDKs) and play an essential, but yet not entirely resolved, role in the regulation of the cell cycle [3].

Anatomical context of SUC1


Associations of SUC1 with chemical compounds


Other interactions of SUC1

  • The two proteins exhibit different patterns of pH dependence with SUC1 being much more active at neutral and slightly acidic pH values than SUC2 [4].
