What's a GeneRIF?

After learning an olfactory discrimination task, no changes in STX gene expression level were observed in the olfactory bulb.
Title: Expression of polysialyltransferases (STX and PST) in adult rat olfactory bulb after an olfactory associative discrimination task.
Results suggest that sialyltransferase-X is probably involved in the proliferation of neural progenitor cells; polysialyltransferase may play a key role in synaptic plasticity of mature neural networks
Title: Dynamic expression of the polysialyltransferase in adult rat hippocampus performing an olfactory associative task.
ST8SiaII/STX expression is essential to allow a correct neuritic development at initial stages of hippocampus ontogeny
Title: Interfering polysialyltransferase ST8SiaII/STX mRNA inhibits neurite growth during early hippocampal development.

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.
