What's a GeneRIF?

TNF-alpha decreases calcium internal mobilization and calcium influx in platelets. TNF-alpha significantly reduced (Tyr 416)-c-Src and (Tyr773)-beta3 subunit of integrin alphaIIbbeta3 phosphorylation.
Title: Platelet activity is negatively modulated by tumor necrosis factor alpha through reductions of cytosolic calcium levels and integrin alphaIIbbeta3 phosphorylation.
Taken together, our results reveal that ND-1 is a novel antagonist of alphaIIb3 with strong antithrombotic effect and lower bleeding risk.
Title: A Naphthalenic Derivative ND-1 Inhibits Thrombus Formation by Interfering the Binding of Fibrinogen to Integrin αIIbβ3.
PI3K/Akt signaling is utilized by alphaIIb-mediated outside-in signaling to activate platelets.
Title: Integrin αIIb-mediated PI3K/Akt activation in platelets.

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.
