Agelenopsis aperta (North American funnel-web spider) (Agelenopsis gertschi)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Insecticidal neurotoxin that induces an irreversible spastic paralysis when injected into insects. Modifies presynaptic voltage-gated sodium channels (Nav), causing them to open at the normal resting potential of the nerve. This leads to spontaneous release of neurotransmitter and repetitive action potentials in motor neurons.1 Publication

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 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.
