| Addtional Information | FUNCTION: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. Toxic to various insects through binding to a high affinity binding site in the insect gut (By similarity).TISSUE SPECIFICITY:Major component of both the cotyledons and embryonic axes of mature seeds.DEVELOPMENTAL STAGE:Increasing expression during seed development followed by a rapid degradation during the first days of seed germination.DOMAIN:The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin (By similarity).PTM:The C-terminal glycine may be removed from PA1b. |
