What's a GeneRIF?

overexpression of ARMS blocked NGF-mediated secretion, without affecting basal secretion, a decrease in ARMS resulted in potentiation. Similar effects were observed with synembryn-B, a protein that interacts directly with ARMS. Downstream of ARMS and synembryn-B are Galphaq and Trio proteins, which modulate the activity of Rac1 in response to NGF
Title: ARMS/Kidins220 and synembryn-B levels regulate NGF-mediated secretion.
Results indicate that a functional N-terminus in C/EBPbeta-LAP* is required for interacting with SWI/SNF and for Ric-8B gene repression in osteoblasts.
Title: A functional N-terminal domain in C/EBPβ-LAP* is required for interacting with SWI/SNF and to repress Ric-8B gene transcription in osteoblasts.
Ric-8BFL-catalyzed nucleotide exchange probably proceeds in the forward direction to produce Galpha-GTP in cells.
Title: Ric-8B is a GTP-dependent G protein alphas guanine nucleotide exchange factor.
two mammalian homologs of the Caenorhabditis elegans protein Ric-8 were identified: Ric-8A (Ric-8/synembryn) and Ric-8B
Title: Mammalian Ric-8A (synembryn) is a heterotrimeric Galpha protein guanine nucleotide exchange factor.

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.
