Description

Predicted to enable RNA binding activity. Acts upstream of or within several processes, including neuromast regeneration; neuron projection development; and positive regulation of oxidative phosphorylation. Part of protein-containing complex. Is expressed in brain; eye; liver; and post-vent region. Used to study spinal muscular atrophy. Human ortholog(s) of this gene implicated in Werdnig-Hoffmann disease; adult spinal muscular atrophy; intermediate spinal muscular atrophy; juvenile spinal muscular atrophy; and spinal muscular atrophy. Orthologous to several human genes including SMN1 (survival of motor neuron 1, telomeric).
