Expressioni

Tissue specificityi

Pancreas and brain.

Developmental stagei

Expressed in early stages of pancreatic development. First expressed in day 8.5 embryos (E8.5) in the dorsal part of the midgut endoderm and by E9.5, in the pancreatic rudiment specifically in early endocrine progenitor cells. At later stages expressed in insulin- or glucagon-producing cells. During neural development, the type 2 PTP-NP is expressed in early stages of neurogenesis, and the type 1 weakly in the later stages.

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.
