TIAM1 je usko povezan sa BAIAP2, kao podjedinicom. Sadrži jedan DH (DBL-homologija) domen, jedan PDZ domen, dva PH-domena i jedan Ras-vezujući RBD-domen.
TIAM1 modulira aktivnost Rho GTP-vezujućih proteina i povezuje vanćelijske signale sa aktivnostima citoskeleta. Osim toga, TIAM1 aktivira Rac1, CDC42 i u manjoj mjeri RhoA.
TIAM1 se nalazi u gotovo svim pregledanim tumorskim ćelijskim linijama, uključujući B– i T-limfom, neuroblastom, melanom i karcinome.
Pokazalo se da invazija limfoma T-ćelija i protein 1 koji indukuje metastaze reaguju sa ANK1,[7] Myc,[8] RAC1[9][10] i PPP1R9B.[11]
Tiam1 također stupa u interakciju s paracingulinom, koji ima ulogu u regrutovanju Tiam1 u spojeve i tako aktivira Rac1 na epitelnim spojevima.[12]
