Pathology & Biotechi

Involvement in diseasei

Retinitis pigmentosa with or without situs inversus (RPSI)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA disorder characterized by variable association of retinitis pigmentosa with situs inversus. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. 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. Situs inversus is a congenital abnormality in which organs in the thorax and the abdomen are opposite to their normal positions due to lateral transposition.

Interactioni

Subunit structurei

Found in a complex with ARL2BP, ARL2 and SLC25A6. Found in a complex with ARL2, ARL2BP and SLC25A4. Interacts with STAT2, STAT3 and STAT4. Interacts with GTP-bound ARL2 and ARL3; the complex ARL2-ARL2BP as well as ARL2BP alone, binds to ANT1. Interaction with ARL2 may be required for targeting to cilia basal body. Interacts with STAT3; interaction is enhanced with ARL2.8 Publications
