'TC10, a Rho family GTPase, has been shown to play an important role in the exocytosis of GLUT4 and other proteins, primarily by tethering the vesicles at the plasma membrane. Using a newly developed probe based on fluorescence resonance energy transfer, we found that TC10 activity at tethered vesicles dropped ... More

The T cell immunoglobulin mucin (Tim) family of receptors regulates effector CD4(+) T cell functions and is implicated in autoimmune and allergic diseases. Tim-3 induces immunological tolerance, and engagement of the Tim-3 immunoglobulin variable (IgV) domain by galectin-9 is important for appropriate termination of T helper 1-immune responses. The 2 ... More
