Phosphoinositide 3-kinase in disease: timing, location, and scaffolding.

abstract：:Protein splicing is a series of enzymatic events involving intramolecular protein breakage, rejoining and intron homing, in which introns are able to promote the recombinative transposition of their own coding sequences. Eukaryotic and prokaryotic spliced proteins have conserved similar gene structure, but little amin...
