Necessary for signaling by class 3 semaphorins and subsequent remodeling of the cytoskeleton. Plays a role in axon guidance. During the axon guidance process, acts downstream of SEMA3A to promote FLNA dissociation from F-actin which results in the rearrangement of the actin cytoskeleton and the collapse of the growth cone. Involved in invasive growth and cell migration. May participate in cytokinesis.

The present study reports that miR-187 was significantly overexpressed in gastric cancer tissues compared to that in non-tumor tissues and was associated with malignant clinical factors such as depth of invasion (P = 0.005), tumor size (P = 0.024), lymph node metastasis .
