RNAseq analysis of alternative splicing in PTBP2 knockout mouse brain

ABSTRACT: The splicing regulator PTBP2 controls a program of embryonic splicing required for neuronal maturation. The splicing regulatory proteins PTBP1 and PTBP2 show distinct temporal expression profiles in the developing brain. Neuronal progenitor cells predominantly express PTBP1, whereas developing neurons express high levels of PTBP2, which are subsequently reduced late in neuronal maturation. We show here that PTBP2 and the program of splicing it controls are essential to proper neuronal maturation and survival. To investigate its in vivo function, we generated conditional PTBP2 null alleles in mice. Loss of PTBP2 in neuronal progenitor cells leads to neonatal death without gross defects in brain architecture. Mice with specific depletion of PTBP2 in the cortex and forebrain are viable. Howev
