Separation of splicing factor SF3 into two components and purification of SF3a activity.
Components required for the splicing of nuclear messenger RNA precursors in vitro have been isolated from HeLa cells. Here we describe the separation of splicing factor SF3 into two components, SF3a and SF3b. Both activities are required together with several other protein factors and U1 and U2 small nuclear ribonucleoproteins for the assembly of a presplicing complex which represents the first...

15 صفحه اولResolution of human transcription factor TFIIIC into two functional components.
tRNA genes and adenovirus viral-associated (VA) genes are transcribed by RNA polymerase III. Transcription of these genes in vitro requires two protein fractions containing transcription factors designated TFIIIB and TFIIIC, in addition to RNA polymerase III. We report that the TFIIIC fraction derived from human cells in culture can be separated into two functional components, which we call TFI...
متن کاملReticulocyte release factor.
Some investigators have had conspicuous success with reticulocyte counting methods in animals as assay techniques for plasma erythropoietic hormone, but there has been some diversity in the reticulocytosis obtained by different workers. This communication reports the disparity between the marrow erythroid activity (assessed by counting colchicine-blocked mitoses) and the reticulocyte response i...
متن کاملSeparation of the bovine colostrum M-1 glycoprotein into two components.
1. Two glycoproteins were isolated from the M-1 acid glycoprotein fraction of bovine colostrum. 2. The lighter glycoprotein had a molecular weight of 7200, contained about 28.4% of carbohydrate, and had an absorption maximum at 275nm. The heavier glycoprotein had a molecular weight of 12000, contained 39.0% of carbohydrate, and had no absorption maxima in the 240-300nm. range of the spectrum. 3...
