Expressioni

Tissue specificityi

Abundant in all cerebral cortical layers, especially the piriform cortex, the pyramidal cells of the CA1-CA3 subfields of the hippocampus, as well as the granular layer of the dentate gyrus. Detected in the internal granular layer and the mitral cell layer of the olfactory bulb; in the medial habenular nucleus; and in amygdaloid, thalamic, hypothalamic, and pontine nuclei. In the cerebellum, found at high levels in the granular layer. Detected in the lateral ventricle. Expression overlaps with 5-HT2C receptor expression in all regions of the brain including the choroid plexus, where 5-HT2C receptors are highly enriched.1 Publication

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.
