SnapShot: Mitochondrial Architecture

Mammals C. elegans 1 TM domain; C-term in IMS and N-term in the matrix. IBM & CJ; self-oligomerizes, binds MICOS/MINOS/MitOS components and Sam50, Tob38, Ugo1, Fzo1. Yeast are viable but exhibit altered mtDNA inheritance and decreased respiratory growth. Mammals and worms exhibit increased ROS production and apoptosis. Loss of CJ, altered cristae structure, accumulation of cristae stacks and cr...

SnapShot: Spliceosome Dynamics III

The complex compositional and conformational dynamics of spliceosomes required for regulated splicing are prone to malfunction when mutations affect splicing factors or cis-acting regulatory sequences. Indeed, many such mutations have been linked to heritable diseases or malignancies in humans. Small molecule modulators and antisense oligonucleotides or analogs harbor great potential for therap...

SnapShot: Spliceosome Dynamics II

Numerous mechanisms exploit or modulate the conformational/compositional dynamics of spliceosomes to regulate splicing. The majority of higher eukaryotic protein-coding genes contain more than one intron and the derived pre-mRNAs can be alternatively spliced. Diverse principles ensure the reliable identification of authentic splice sites while concomitantly providing flexibility in splice site ...
