What's a GeneRIF?

The deletion of IA-2 and IA-2beta results in multiple pathophysiologic changes and represents a unique in vivo model for studying the effect of hormone and neurotransmitter reduction on known and still unrecognized targets.
Title: Pathophysiologic changes in IA-2/IA-2β null mice are secondary to alterations in the secretion of hormones and neurotransmitters.
Ptprn is an activity dependent gene in mouse olfactory sensory neurons. [Ptprn]
Title: Activity-dependent genes in mouse olfactory sensory neurons.
Data show that miRNAs are involved in regulating the expression of the major type 1 diabetes (T1D) autoantigens IA-2, IA-2beta, and GAD65 enzyme.
Title: Multiple microRNAs within the 14q32 cluster target the mRNAs of major type 1 diabetes autoantigens IA-2, IA-2β, and GAD65.
Experiments showed that the knock-out of IA-2, but not IA-2beta, resulted in marked impairment of active avoidance learning; one copy of the gene was sufficient to maintain active avoidance learning
Title: The dense core vesicle protein IA-2, but not IA-2β, is required for active avoidance learning.
Data show that the insulinoma associated protein-2 distribution in peripheral neurons appeared more intensely in neurites rather than in the cell bodies.
Title: Localization of insulinoma associated protein 2, IA-2 in mouse neuroendocrine tissues using two novel monoclonal antibodies.
IA-2-/- mice had higher sensitivity to STZ, suggesting a role of IA-2 not only in the secretion but also in the production of insulin.
Title: Insulinoma-associated protein 2-deficient mice develop severe forms of diabetes induced by multiple low doses of streptozotocin.
IA-2 and IA-2beta are dispensable for exocytosis of insulin granules, but are probably more important for cargo loading and/or stability of dense core vesicles
Title: Insulin secretion in islets from mice with a double knockout for the dense core vesicle proteins islet antigen-2 (IA-2) and IA-2beta.
In mice IA-2 expressed exclusively in dense core secretory vesicles (DCV) of neuroendocrine cells of brain and impairment of conditioned learning.
Title: Disturbances in the secretion of neurotransmitters in IA-2/IA-2beta null mice: changes in behavior, learning and lifespan.
ICA512-CCF also dimerizes with intact ICA512 on granules, thereby displacing it from beta2-syntrophin.
Title: Regulation of insulin granule turnover in pancreatic beta-cells by cleaved ICA512.
IA-2 beta undergoes at least three distinct proteolytic cleavages.
Title: Detection of proteolytic cleavages of diabetes-associated protein IA-2 beta in the pancreas and the brain using novel anti-IA-2 beta monoclonal antibodies.

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.
