Fascins are actin cross-linking proteins that function in the organisation of two major forms of actin-based structures: dynamic, cortical cell protrusions and cytoplasmic microfilament bundles [].This entry represents fascin-2 (FSCN2), which cooperates with beta-actin to maintain the stereocilia length. Stereocilia are actin-based protrusions on auditory sensory hair cells [].
