Sex-determination protein fem-3
Feminization of XX and XO animals protein 3
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Required for male development. In XO (male) animals, fem-3 directs male differentiation in all tissues. In XX (hermaphrodite) animals, it specifies the first 80 or so germ cells to be sperm. Negatively regulates male development when bound to tra-2. Together with fem-2 associates with the CBC(fem-1) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of tra-1.
