Pathology & Biotechi

Disruption phenotypei

Mice are born at the expected Mendelian ratio, but exhibit severe growth retardation and impaired erythropoiesis. None survive the first day of postnatal life. PPP1R15A-PPP1R15B double-knockout embryos do not develop past the preimplantation period.1 Publication

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.
