FNBP3 Binds to WASL/N-WASP and suppresses its translocation from the nucleus to the cytoplasm, thereby inhibiting its cytoplasmic function. 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. May be involved in pre-mRNA splicing. Belongs to the PRPF40 family. Expressed in the brain cortex (at protein level). Widely expressed. 4 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
