Structural highlights

Disease

[PRPF3_HUMAN] Defects in PRPF3 are the cause of retinitis pigmentosa type 18 (RP18) [MIM:601414]. RP leads to degeneration of retinal photoreceptor cells. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. RP18 inheritance is autosomal dominant.^{[1] [2] [3]}

Function

[PRPF3_HUMAN] Participates in pre-mRNA splicing. May play a role in the assembly of the U4/U5/U6 tri-snRNP complex.
