Pathology & Biotechi

Disruption phenotypei

Worms exhibit arrested development after embryogenesis. Viable mutants appear lethargic with sporadic jerky movements and absent M3 pharynx motorneuron activity. All mutants are resistant to the acetylcholinesterase inhibitor aldicarb indicating impaired cholinergic transmission.1 Publication

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.
