    Summary
    Involved in several processes, including negative regulation of opsin-mediated signaling pathway; response to sucrose; and triglyceride homeostasis. Located in several cellular components, including cilium; neuronal cell body; and rhabdomere. Is expressed in several structures, including endoderm anlage; head epidermis primordium; mesoderm; sensory nervous system primordium; and sensory neurons. Human ortholog(s) of this gene implicated in Leber congenital amaurosis 15; retinitis pigmentosa; and retinitis pigmentosa 14. Orthologous to several human genes including TULP1 (TUB like protein 1).

    What's a GeneRIF?
    1. This is the first demonstration that dTULP regulates TRP channel localization in cilia, and suggests that dTULP is a protein that regulates ciliary neurosensory functions.
