InnateDB Annotation
Summary
GNAI2 is regulated by TLR signalling and plays an anti-inflammatory role in endotoxema and polymicrobial sepsis. (Demonstrated in murine model)
Sustained activation of GNAI2 dampens TNF and IL6 production stimulated by TLR2/4 ligands. (Demonstrated in mice)
InnateDB Annotation from Orthologs
Summary
[Mus musculus] Gnai2 is regulated by Tlr signaling and plays an anti-inflammatory role in endotoxema and polymicrobial sepsis.
[Mus musculus] Sustained activation of Gnai2 dampens Tnf and Il6 production stimulated by Tlr2/4 ligands.
Entrez Gene
Summary The protein encoded by this gene is an alpha subunit of guanine nucleotide binding proteins (G proteins). The encoded protein contains the guanine nucleotide binding site and is involved in the hormonal regulation of adenylate cyclase. Several transcript variants encoding different isoforms have been detected for this gene, but the full-length nature of only two are known so far. [provided by RefSeq, Oct 2009]
