Expressioni

Tissue specificityi

Detected in brain and skin (at protein level). Detected in brain white matter, cerebellum forebrain, stomach, kidney, skin and testis. Detected in oligodendrocytes.2 Publications

Developmental stagei

Levels increase rapidly in brains from newborns, in parallel with myelination in the central nervous system. Present at very low levels in newborns. Levels are highest at 2 to 3 weeks, and then decrease slightly to reach an constant, intermediate level after 4 months. Constitutively expressed at an intermediate level throughout adult life.2 Publications

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.
