A familial Danish dementia rat shows impaired presynaptic and postsynaptic glutamatergic transmission.
Title: A familial Danish dementia rat shows impaired presynaptic and postsynaptic glutamatergic transmission.
the resulting BRI2 brain interactome, associates this protein with neurite outgrowth and neuronal differentiation, as well as synaptic signalling and plasticity. It follows that further studies should address BRI2 particularly given its relevance to neuropathological conditions.
Title: Identification and characterization of the BRI2 interactome in the brain.
Itm2b expression was detected strong in the rat testis, epididymis, and vas deferens from day 1 - 70. When the rats were castrated or treated with ethylene dimethane sulfonate (EDS), Itm2b expression was protected in the epididymis and vas deferens by administered testosterone.
Title: Differential expression and regulation of integral membrane protein 2b in rat male reproductive tissues.
by modulating BRI2 processing using an ADAM10 inhibitor, a dual role for BRI2 in neurite outgrowth is suggested: phosphorylated full-length BRI2 appears to be important for the formation of neuritic processes, and BRI2 NTF promotes neurite elongation.
Title: BRI2 Processing and Its Neuritogenic Role Are Modulated by Protein Phosphatase 1 Complexing.
when BRI2 is phosphorylated a significant increase in neuronal outgrowth and differentiation is evident
Title: BRI2 and BRI3 are functionally distinct phosphoproteins.

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.
