Description
6 coding exons covering 18095 bp on chromosome 1
Proteins
Expression
ubiquitous ; higher in brain and hemopoïetic tissues
Localisation
Rap1 is bound to membranes. In many cell types, it is found in a perinuclear compartment overlapping the Golgi. Rap1 proteins (A and B) are phosphorylated near the C-ter by cAMP-dependent protein kinase. This results in translocation of part of the Rap1 pool to the cytosol.
Function
The function of Rap1 is still a matter of debate. Its overexpression is able to compete with the activation of Raf-1 by active Ras. Active Rap1B has been shown to activate the B-Raf kinase and the MEK-ERK cascade. In several cellular models, Rap1 has been shown to be involved in the regulation of integrin-mediated cell adhesion.
Homology
95% to Rap1B, 60% identical to Rap2, 50 % to Ras proteins
