Expressioni

Tissue specificityi

Expressed in cerebral cortex and cerebellum. Expressed in retina (at protein level).4 Publications

Developmental stagei

Expression starts at E16 in the cerebral cortex and increases to reach a maximum 20 days after birth. Then it decreases till adulthood to be expressed half of the peak level. In the retina, expression reaches a maximum at postnatal day 14 (P14). It starts weakly at E16 in the retinal pigment epithelium (RPE). At P0 it is detected in nerve fiber layer (NFL), ganglion cell layer (GCL), inner plexiform layer (IPL) and RPE. At P7, it becomes intense in the NFL and IPL. At P14, expression becomes intense in the area of outer segments (OS) of the photoreceptor cells as well as in RPE, whereas in the inner layers it becomes gradually fainter. From P21 to P42, it decreases in inner retinal layers. OS and RPE still express, whereas expression in the NFL and IPL decreases (at protein level).2 Publications

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.
