Pre-mRNA-processing factor 40 homolog A (PRPF40A)

Binds to WASL/N-WASP and suppresses its translocation from the nucleus to the cytoplasm, thereby inhibiting its cytoplasmic function (By similarity). Plays a role in the regulation of cell morphology and cytoskeletal organization.

Required in the control of cell shape and migration. May play a role in cytokinesis.
