Sef1 which is a putative transmembrane protein of the Golgi apparatus seems to be a scaffold protein that recruits ERK1/2 and MEK1/2 to its vicinity and probably allows their activation by Golgi-localised Ras proteins.

Upon activation scaffold proteins serve as platforms in which ERK dimers are assembled forming complexes capable of interacting with and activating cognate cytoplasmic substrates.
Unlike many other scaffolds ERK1/2 do not dissociate from Sef1 upon stimulation and therefore nuclear translocation of the Sef1 anchored fraction of ERK1/2 molecules is blocked.

MEK is continuously dephosphorylated by PP2A (PPP2CA) whose activity is stimulated by P38: P38 activity increases the physical association between PP2A and MEK/ERK complex. A direct interaction between P38 and ERK has been proposed as a mechanism to inhibit ERK phosphorylation. AP-1 mediated gene expression inhibits ERK phosphorylation.

RSK2 is a well known ERK substrate in the cytoplasm and has been shown to undergo autophosphorylation after ERK phosphorylation.
RSKs interact with ERK and dissociate upon activation.
Results suggested that KSR1 was the scaffold utilised by ERK1/2 for activating cPLA2 but not RSK1.
