| abstractText | Multiple heat shock cognate (hsc70) cDNA clones were isolated from the mouse embryonal carcinoma cell line F9. They all encode a single 72-kDa protein, which is constitutively expressed in all mouse cell lines and tissues tested, and which is only slightly induced by hyperthermia. hsc70 RNA is very abundant in F9 stem cells and brain, but very little is found in 14-day-old embryos. Upon differentiation of F9 stem cells induced by retinoic acid and cyclic AMP, expression of the hsc70 gene decreases only slightly, suggesting that hsc70 is highly expressed in early mouse development and is then down-regulated towards the end of embryogenesis. In adult tissues only the brain retains the high level of hsc70 gene expression found in F9 stem cells. We also show that expression of hsc70 protein and clathrin is uncoupled in F9 cells, indicating that the uncoating activity of coated vesicles may not be the only function of hsc70 protein. |
