Downstream intronic splicing enhancers
AbstractAlternative splicing leads to multiple proteins from individual genes and the most common deviation from the norm is precise exon omission. Mutations that cause this can be found deep in introns, especially downstream of the cassette exon. This review summarises what is known about these intronic splicing enhancers and their RNA-binding proteins that cause spliceosome assembly on the upstream exon
Distributional fixed point equations for island nucleation in one dimension: a retrospective approach for capture zone scaling
The distributions of inter-island gaps and captures zones for islands
nucleated on a one-dimensional substrate during submonolayer deposition are
considered using a novel retrospective view. This provides an alternative
perspective on why scaling occurs in this continuously evolving system.
Distributional fixed point equations for the gaps are derived both with and
without a mean field approximation for nearest neighbour gap size correlation.
Solutions to the equations show that correct consideration of fragmentation
bias justifies the mean field approach which can be extended to provide
closed-from equations for the capture zones. Our results compare favourably to
Monte Carlo data for both point and extended islands using a range of critical
island size . We also find satisfactory agreement with theoretical
models based on more traditional fragmentation theory approaches.Comment: 9 pages, 7 figures and 1 tabl
