Functioni

Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems (Probable). May play a role in resistance to fungal infection in the epidermis by regulating the up-regulation of several antimicrobial peptides of the NLP and CNC families (PubMed:22470487, PubMed:19380113). Upstream of plc-3, tpa-1 and the p38-like pathway, required for the expression of antimicrobial peptide nlp-29 in the epidermis in response to fungal infection or physical injury (PubMed:19380113).Curated2 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
