Plays a key role in the organization of epithelial monolayers by regulating the actin cytoskeleton. May be involved in ovary development (By similarity). Interacts with nonmuscle actin. Expression absent in adult ovary. Expressed in ovary between 16.5 dpc and P5. It is uncertain whether Met-1 or Met-2 is the initiator. The first methionine is not conserved among other organisms, but rat. It could be rodent-specific.
