4JIF - PubMed Abstract: 
Integrin cytoplasmic domain-associated protein-1 (ICAP1) is a suppressor of integrin activation and directly binds to the cytoplasmic tail of β1 integrins; its binding suppresses integrin activation by competition with talin. Krev/Rap1 interaction trapped-1 (KRIT1) releases ICAP1 suppression of integrin activation by sequestering ICAP1 away from integrin cytoplasmic tails ...
