靶點詳情

功能：

Contributes to the organization of the actin cytoskeleton and cell shape. Plays a role in the formation of lamellipodia and in cell migration. Plays a role in the regulation of neuron morphology, axon growth and formation of neuronal growth cones. Through its interaction with CTTNBP2, involved in the regulation of neuronal spine density. Plays a role in the invasiveness of cancer cells, and the formation of metastases. Plays a role in focal adhesion assembly and turnover. In complex with ABL1 and MYLK regulates cortical actin-based cytoskeletal rearrangement critical to sphingosine 1-phosphate (S1P)-mediated endothelial cell (EC) barrier enhancement. Plays a role in intracellular protein transport and endocytosis, and in modulating the levels of potassium channels present at the cell membrane. Plays a role in receptor-mediated endocytosis via clathrin-coated pits. Required for stabilization of KCNH1 channels at the cell membrane.
