The modulation of integrin affinity is central to platelet and leukocyte function. Two proteins, talin and kindlin, that interact with distinct regions of integrin cytoplasmic domains, have been shown to play essential roles in inducing the high affinity integrin conformation required for platelet and leukocyte adhesive interactions.Here we highlight some of the key studies that have described roles for talin and kindlin in integrin function and discuss several models that explain how talin and kindlins might work together to regulate integrin activation.
