Expressioni

Tissue specificityi

In the embryo, expressed in gastric caeca, midgut cells of the proventriculus, and in the mid and hindgut. In the larval and adult gut brush border, expressed in the microvilli. Also expressed at high levels in follicle cells during oogenesis.1 Publication

Developmental stagei

Expression starts at 8-12 hours embryonic development, continues to increase until third larval instar, disappears in pupae and is present at a low level in adults. Expression in embryogenesis is correlated with the formation of a brush border within the alimentary canal.2 Publications

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.
