Estimated half-life:
The N-terminal of the sequence considered is M (Met).
The estimated half-life is: 30 hours (mammalian reticulocytes, in vitro).
>20 hours (yeast, in vivo).
>10 hours (Escherichia coli, in vivo).
Instability index:
The instability index (II) is computed to be 38.95
This classifies the protein as stable.
Aliphatic index: 98.47
Grand average of hydropathicity (GRAVY): -0.122
