    basic FUNCTION
  • PIP3 dependent GAP that regulates Arf, Rho and Cdc42 dependent cell activities
  • is an Arf6GAP that functions downstream of RHOA to regulate focal adhesion dynamics
  • slow cell spreading and promote Focal adhesions (FAs) dependent on its ArfGAP activity
  • reduced expression of ARAP2 resulted in an easily detectable increase in total RAC1
    • CELLULAR PROCESS

    DNA
    RNA
    small molecule
    protein
  • changes in ARF6 and RAC1 activities are necessary but not sufficient for ARAP2 to promote the growth of Focal adhesions (FAs)
  • through regulation of ARF6, ARAP2 may control the recycling of integrins or other adhesion components, leading to a change in the adhesion turnover
  • ARAP2 and ACAP1 had opposing effects on apparent ITGB1 internalization
    • cell & other
  • targeted by phosphatidyl inositol (3,4,3) triphosphate
