Expressioni

Developmental stagei

Maximum levels are found in 35 day old plantlets when the rosette is mature, consisting of 8-10 fully expanded leaves, and as the floral stem starts to form. This level remains constant during the further life span of the plant.

Inductioni

By dark adaptation. This gives a 20-fold increase in expression.

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.
