Expressioni

Developmental stagei

Transcripts accumulate when morphogenesis begins with mesenchyme cell ingression and gastrulation. Accumulation in all cell types of the embryo, although hybridization shows that they are somewhat enriched in cells of oral ectoderm and endoderm. Isoform 2 transcript is enriched in endomesoderm.

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.
