Summary: Enables mRNA binding activity. Involved in several processes, including negative regulation of cold-induced thermogenesis; regulation of alternative mRNA splicing, via spliceosome; and regulation of axon guidance. Acts upstream of or within regulation of RNA metabolic process. Predicted to be active in cytoplasm and nucleus. Is expressed in several structures, including central nervous system; olfactory epithelium; peripheral nervous system ganglion; retina; and trigeminal nerve. Orthologous to human NOVA2 (NOVA alternative splicing regulator 2). [provided by Alliance of Genome Resources, Oct 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
