Anti-NOVA1 antibodies are used in the immunodetection of the protein NOVA alternative splicing regulator 1. In humans, the canonical protein has a reported length of 507 amino acid residues and a mass of 51.7 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in cerebellum, brain stem, hippocampus, and frontal cortex. NOVA1 is reported to function to regulate alternative splicing in neurons by binding pre-mRNA in a sequence-specific manner to activate exon inclusion or exclusion. Synonyms for this target antigen include neuro-oncological ventral antigen 1, onconeural ventral antigen 1, paraneoplastic Ri antigen, ventral neuron-specific protein 1, and RNA-binding protein Nova-1. NOVA1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of NOVA1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
