  WB analysis of HeLa using 82309-1-RR

  Non-treated and Forskolin treated HeLa cells were subjected to SDS PAGE followed by western blot with 82309-1-RR (Phospho-RASGRF1 (Ser927) antibody) at dilution of 1:2500 incubated at room temperature for 1.5 hours. The membrane was stripped and re-blotted with mTOR (66888-1-Ig) as loading control.

Background Information

The RASGRF1 exchange factor, which is also known as CDC25 in Saccharomyces cerevisiae, promotes the exchange of Ras-bound GDP by GTP, is known to play central roles in pathways of cellular growth and differentiation. The serine residue at position 916 in mouse Ras-GRF1 is a PKA phosphorylation site, and the corresponding human residue is serine 927. It's reported that phosphorylation of serine 916 is necessary but not sufficient for maximal activation of mouse RASGRF1. The calculated MW of non-phosphorylated RASGRF1 is 145 kDa. 82309-1-RR can detect a band around 145 kDa, and can detect the increasing phosphorylation level after Forskolin treated.(PMID:15853814, 10601308)
