Enables mRNA binding activity. Acts upstream of or within several processes, including long-chain fatty acid biosynthetic process; positive regulation of macromolecule metabolic process; and vasculogenesis. Located in cytoplasm; nucleus; and synapse. Is expressed in several structures, including alimentary system; central nervous system; craniocervical region bone; reproductive system; and sensory organ. Orthologous to human QKI (QKI, KH domain containing RNA binding). [provided by Alliance of Genome Resources, Apr 2022]
