Caution

This protein, although sequenced from the genome of strain 74-OR23-1A, has only limited sequence identity to the corresponding protein produced by the locus NCU07340 determined in the complete genome sequence of Neurospora crassa 74-OR23-1A, due to extensive nucleotide sequence discrepancies mostly in the N-terminus.Curated

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.
