Technical Data
A0928
AFX, phosphorylated (Ser193)
Description:
The Forkhead family of transcription factors is involved in tumorigenesis in rhabdomyosarcoma and acute leukemias. Within the family, three members (FKHR, AFX and FKHRL1) have sequence similarity to the nematode homologue DAF- 16, which has been shown to mediate signaling via a pathway involving IGFR1, PI3K and Akt. There are three Akt phosphorylation sites in the FKHR proteins: Thr24, Ser256 and Ser319. Phosphorylation of FKHR family members at these sites by Akt promotes cell survival and regulates the cell cycle. Phosphorylation regulates FKHR nuclear translocation and target gene transcription.

Applications:
Suitable for use in Western Blot and ELISA. Other applications have not been tested.

Recommended Dilution:
Western Blot: 1:1000
Optimal dilutions to be determined by the researcher.

Molecular Weight: 65kD

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage, store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
