Expressioni

Tissue specificityi

Head and ventral nerve cord from embryos to adults. Expressed in many sensory neurons. Subset of head neurons show coexpression with daf-4 when dauer/nondauer decision is made. Also expressed in non-neuronal cells: membraneous sheath surrounding the distal end of the intestine and in the distal tip cell of the gonad.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.
