Disruption phenotypei

Slower than normal migration of granule cells in the developing cerebellum, leading to a decreased cerebellum size in adult mice and impaired skills in tasks that require coordinated movement and balance. Granule cells from mutant mice have a rounded shape and lack the elongated shape seen in wild-type. At 6 days after birth, increased granule cell apoptosis is observed, contrary to the situation in wild-type.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.
