Caution

According to PubMed:18629938, the SIGLECP16 sequence, that was initially classified as a pseudogene, has a 4 bp deletion when compared with the sequence shown in this entry. This deletion is a polymorphism with a frequency of around 50% in the UK population. The frameshifted allele is non-functional whereas the sequence displayed here seems to be functional. The functional allele has been named SIGLEC16 in PubMed:18629938.Curated

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.
