Function

Causative gene for retinitis pigmentosa (20705278). Retinal ciliopathy protein that is part of connecting cillium complex. Interacts with CEP290, lebercin, OFD1 and SDCCAG8. These interactions suggest that FAM161A could be involved in protein transport and docking between the inner segments and outer plexiform layer (22940612). Component of microtubule- organizing centers that associates with the intracellular microtubule network to increase the acetylation of α-tubulin. Involved in microtubule stabilization to maintain the microtubule tracks and/or in transport processes along cytoplasmic and ciliary (24664697, 22791751).
