ULK1 and autosomal dominant retinitis pigmentosa: The aberrant AS of ULK1 (unc-51 like autophagy activating kinase 1), a key initiation factor capable of being phosphorylated by mTOR and AMPK at distinct residues for autophagy induction, has been linked to autosomal dominant retinitis pigmentosa caused by the deficiency of splicing factor PRPF8 [24].
