Expressioni

Developmental stagei

Expressed in a spatially restricted manner in embryos 8.5 dpc, expression is limited to the CNS with an anterior boundary in the hindbrain and extending posteriorly through caudal regions of the spinal cord. The same spatial expression is seen in embryos 9.5 to 12.5 dpc.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.
