Expressioni

Tissue specificityi

Expressed specifically in embryo and adult vascular endothelium.1 Publication

Developmental stagei

In embryonic development of vascular endothelium shows a dynamic expression pattern within vessels, with expression starting in the larger axial vessels and intersomitic vessels at earlier ages, and changing to intersomitic vessel and capillary expression at later stages. At E9.0, is expressed in the central vessels, the dorsal aorta, and intersomitic vessels. At E9.5, is highly expressed in intersomitic vessels with little expression remaining in dorsal aortae. By E10.0, is detected in capillary vessels, the capillary plexus of the limb buds, and throughout the endothelium as microvessels sprout from the dorsal aortae. No expression was detected in the neural tube at E9.0 and E9.5. However, it is detected within the capillaries sprouting into the neural tube, as well as in the adjacent perineural capillary plexus at E10.0.1 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.
