Transforming protein Myb

Gene

V-MYB

Organism
Avian myeloblastosis virus
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

DNA-binding protein that specifically recognizes the sequence 5'-YAAC[GT]G-3'. The v-Myb oncogene transforms immature myelomonocytic avian cells in culture and induces myeloblastosis (myeloid leukemia) in chickens.

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.
