Immunofluorescent analysis of Cdc37 in A431 cells. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with a Cdc37 monoclonal antibody (Product # MA3-029) at a dilution of 1:200 overnight at 4 C, washed with PBS and incubated with a DyLight-488 conjugated secondary antibody (Product # 35503). Cdc37 staining (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Images were taken at 60X magnification.

MA3-029 detects Cdc37 from hamster, human, mouse and rat cells and tissues.
MA3-029 has been successfully used in Western blot, FACS, immunofluorescence, immunocytochemistry and immunoprecipitation (under denaturing conditions) procedures. By Western blot, this antibody recognizes a single 50 kDa protein representing Cdc37 in HeLa cell extract. Immunofluorescence staining of Cdc37 in Hepa1 cells with MA3-029 results in mostly cytoplasmic staining concentrated around the nuclear membrane. This antibody detects some weak non-specific bands in Jurkat, A431 and NIH-3T3 cell lysates.
The MA3-029 antigen is purified mouse Cdc37 fusion protein.
In S. cerevisiae, Cdc37 has been shown to be an important regulator of cell division cycle through its action on cyclin-dependent kinases (CDK's). Cdc37 has also been associated with signaling pathways and kinases unrelated to cell cycle control, including v-Src, casein kinase II, MPS1 kinase and the sevenless receptor tyrosine kinase. Interestingly, HSP90 has also been shown to be associated with many of the same cellular targets as Cdc37.
It has now been shown that Cdc37 is the same protein previously described as p50 which has been found to be associated with many of the same proteins as HSP90. Among others, Cdc37/p50 has been found complexed with Src-family kinases (Fyn, Yes, Fes, Lck & Fgr), Raf and pp60v-src. More recently, Cdc37 has been shown to be a chaperone independently and in concert with HSP90. In fact, Cdc37 is necessary for the binding of HSP90 to Cdk4.
