Dynamics of autophagosome formation: a pulse and a sequence of waves.

abstract：:AS (alternative splicing) is a post-transcriptional process which regulates gene expression through increasing protein complexity and modulating mRNA transcript levels. Regulation of AS depends on interactions between trans-acting protein factors and cis-acting signals in the pre-mRNA (precursor mRNA) transcripts, ter...
