What's a GeneRIF?

CgB is necessary for efficient trafficking of secretory proteins into the budding granule, which impacts the availability of insulin-containing secretory granules for exocytic release.

Possible involvement of Stat3 and Prlh1/Chgb up-regulation in the transition from short to repeated stress activation.
Title: A systems approach identifies co-signaling molecules of early growth response 1 transcription factor in immobilization stress.
When released extra-cellulary, CHGB proteolytic fragments exert a feedback effect to inhibit catecholamine secretion.

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.
