However , DNA synthesis by pol epsilon was stimulated up to 10 fold upon addition of the three auxiliary proteins PCNA , RF C and SSB . ^^^ This stimulation of pol epsilon by PCNA / RF C / SSB appears to be the superposition of two events : pol epsilon holoenzyme ( pol epsilon , PCNA , RF C ) synthesized longer products than its pol epsilon core counterpart , but elongated less primers . ^^^

Drosophila cyclin B transcripts direct posterior pole accumulation late in oogenesis and peri nuclear association in syncytial embryos . ^^^ These transcripts become evenly distributed throughout the oocyte cytoplasm but , in addition , those of cyclin B become concentrated at the posterior pole . ^^^ Examination of the distributions of RNAs transcribed from chimeric cyclin genes indicates that sequences in the 3 ' untranslated region of the larger cyclin B RNA are required both for it to become concentrated at the posterior pole and to direct those transcripts in the body of the syncytial embryo to their peri nuclear localisation . ^^^

Yeast Pol epsilon required the presence of a DNA binding protein ( SSB ) whereas human Pol epsilon required the addition of SSB , Activator 1 and proliferating cell nuclear antigen ( PCNA ) for maximal activity . ^^^ Like Pol delta , Pol epsilon formed complexes with SSB coated primed DNA templates in the presence of Activator 1 and PCNA which could be isolated by filtration through Bio Gel A 5m columns . ^^^

Transcripts of one of two Drosophila cyclin genes become localized in pole cells during embryogenesis . ^^^ We show that both genes encode abundant maternal mRNAs , but whereas the cyclin A mRNA is relatively uniformly distributed before cell formation , the cyclin B mRNA becomes localized to the developing pole cells . ^^^

Discrete sequence elements control posterior pole accumulation and translational repression of maternal cyclin B RNA in Drosophila . ^^^ The concentration of cyclin B transcripts at the posterior pole of the Drosophila oocyte occurs at a late stage of oogenesis and is dependent on the sequence in the 3 ' untranslated part of the RNA . ^^^ We show that RNA injected into the posterior cytoplasm of syncytial embryos accumulates in the pole cells if it contains sequences present in the 3 ' untranslated region of maternal cyclin B transcripts . ^^^ Zygotic transcription directed from the cyclin B promoter does not begin in the pole cells until the first instar larva has hatched . ^^^

BACKGROUND : Fission yeast microtubule associating protein ( MAP ) p93Dis1 functions for sister chromatid separation : dis 1 mutants fail to separate chromosomes , while the spindle elongates but without cyclin destruction . p93Dis1 localizes along microtubules in interphase cytoplasm , but shifts to the spindle pole body ( SPB ) and spindle microtubules upon the entry into mitosis . ^^^

The importance of the interdomain connector loop and of the carboxy terminal domain of Saccharomyces cerevisiae proliferating cell nuclear antigen ( PCNA ) for functional interaction with DNA polymerases delta ( Poldelta ) and epsilon ( Pol epsilon ) was investigated by site directed mutagenesis . ^^^ Interestingly , the pol 30 79 mutant PCNA ( pcna 79 ) was most defective in replication with Poldelta , whereas pcna 90 was defective in replication with Pol epsilon . ^^^ Protein protein interaction studies showed that pcna 79 and pcna 90 failed to interact with Pol delta and Pol epsilon , respectively . ^^^

Cleavage does not occur during necrosis or following exposure to H ( 2 ) O ( 2 ) or methanesulfonic acid methyl ester . p 140 is unlikely to be able to functionally replace p 261 in vivo , since it does not bind to PCNA or the other pol epsilon subunits . . ^^^
