Functioni

PA1b binds to basic 7S globulin (BG) and stimulates its phosphorylation activity. Involved in the signal transduction system to regulate the growth and differentiation as a hormone peptide (By similarity). Toxic to various insects through binding to a high affinity binding site in the insect gut.By similarity2 Publications

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.
