What's a GeneRIF?

Data indicate that mutations at different sites affect the ability of rap GTP-Binding Protein Rap1 to activate appropriately.
Title: The structure and conformational switching of Rap1B.
specific activation of Rap1B contributes to neuronal polarization via interaction with RalA and Nore1A in addition to PI3-kinase.
Title: Longest neurite-specific activation of Rap1B in hippocampal neurons contributes to polarity formation through RalA and Nore1A in addition to PI3-kinase.
These data establish rap1b as a novel gene rapidly induced by GnRH and a candidate to modulate gonadotropin secretion in rat gonadotropes.
Title: Optimized amplification and single-cell analysis identify GnRH-mediated activation of Rap1b in primary rat gonadotropes.
Inhibition of PI3K or mTOR reduced the level of Rap1B, which acts downstream of Rheb and mTOR. The ubiquitin E3 ligase Smurf2 mediates the restriction of Rap1B by initiating its degradation.
Title: Rheb and mTOR regulate neuronal polarity through Rap1B.
analysis of a cAMP-Epac/PKA-Rap1b-PP2A signaling module involved in Akt regulation that may represent a physiological event in the process of cAMP stimulation of thyroid mitogenesis
Title: A novel Epac-Rap-PP2A signaling module controls cAMP-dependent Akt regulation.
cAMP inhibits Akt via Rap1b
Title: cAMP inhibition of Akt is mediated by activated and phosphorylated Rap1b.
On the mitogenic properties of Rap1b: cAMP-induced G(1)/S entry requires activated and phosphorylated Rap1b.

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.
