What's a GeneRIF?

NUCB1 mRNA and protein was found to be present in all brain regions, extending to the spinal cord and dorsal root ganglia; the protein was detected in cell somata and proximal dendrites, but not in axons or terminal structures. Further examination of the subcellular distribution of NUCB1 using organelle-specific markers revealed its consistent presence in the Golgi apparatus.
Title: Nucleobindin 1 (NUCB1) is a Golgi-resident marker of neurons.
a wide distribution of phoenixin in the hypothalamus which could implicate a potential functional relationship with nesfatin-1, possibly in the regulation of the hypothalamic-pituitary-gonadal axis or other autonomic functions
Title: The novel neuropeptide phoenixin is highly co-expressed with nesfatin-1 in the rat hypothalamus, an immunohistochemical study.
When administrated by injection into the fourth ventricle, nesfatin-1 suppressed food intake in comparison with the control vehicle.

structural basis for the properties of Calnuc and NUCB2 binding to Galpha subunits and its regulation by calcium ions.
Title: G Protein binding sites on Calnuc (nucleobindin 1) and NUCB2 (nucleobindin 2) define a new class of G(alpha)i-regulatory motifs.
Nucleobindin 1 is a calcium-regulated guanine nucleotide dissociation inhibitor of G{alpha}i1.

Nucleobindin expression is low during bone cell proliferation, upregulated during differentiation and matrix maturation, but subsequently downregulated during the mineralization process.
Title: Nucleobindin is produced by bone cells and secreted into the osteoid, with a potential role as a modulator of matrix maturation.

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.
