NCIt definition : Human NOVA2 wild-type allele is located in the vicinity of 19q13.3 and is approximately
34 kb in length. This allele, which encodes RNA-binding protein Nova-2, plays a role
in the regulation of RNA splicing or metabolism in a specific population of developing
neurons.;
NCIt note : Expressed in brain, human NOVA2 Gene encodes RNA-binding NOVA2 protein, recognized
by the paraneoplastic syndrome antibody anti-Ri. NOVA1 and NOVA2 bind to similar RNA
ligands with high affinity and may regulate RNA splicing. The NOVA2 KH3 domain interacts
with single-stranded RNA; KH3 bound to stem loop RNA resembles a vise, with UCAC held
between an invariant Gly-X-X-Gly motif and a variable loop. Tetranucleotide recognition
is supported by an aliphatic alpha-helix/beta-sheet RNA-binding platform that mimics
UG by making Watson-Crick-like hydrogen bonds with CA.;
