NOVA1 (E9E6U) Rabbit mAb #65350

Neuro-oncological ventral antigen (NOVA) 1 and 2 are neuronal RNA-binding proteins (RBPs) that bind YCAY motifs to regulate alternative splicing (1-3). Both proteins have been shown to be targets in paraneoplastic opsoclonus myoclonus ataxia, a neuronal autoimmune disease (1,3). NOVA proteins rely on their KH3 domain to bind RNA and are reciprocally expressed in various parts of the brain (4). NOVA1 has been shown to be essential for neuronal viability, as it controls alternative splicing in GlyRalpha2 and GABA(A) receptor pre-mRNAs (5). NOVA1 is also capable of auto-regulation as it binds to its own exon 4, which contains a phosphorylated protein domain (6). NOVA1/2 double knockout mice are paralyzed due to lack of alternatively spliced agrin Z(+), which helps synapse formation at neuromuscular junctions (7). NOVA2 has been shown to regulate circular RNA biogenesis in the developing brain (8). NOVA1 has been shown to be highly expressed in many different cancer types, and can promote epithelial-mesenchymal transition by binding β-catenin mRNA (9,10).
