Description

This entry represents protein unc-119 homologue A (UNC119) from vertebrates, also known as retinal protein 4 (RG4) [PMID: 9538874], and the homologue from Drosophila [PMID: 10858820]. It is highly expressed in retinal photoreceptor inner segments and synaptic regions. Nevertheless, UNC119 has been detected in leukocytes (eosinophils), T-cells, lung fibroblasts, the adrenal glands, cerebellum and kidney. It interacts with several diverse proteins, such as Arf-like GTPases ARL2/ARL3 [PMID: 12527357, PMID: 18588884] and the Ca2+-binding protein CaBP4 [PMID: 18296658]. It has been shown to activate Src-type tyrosine kinases associated with the interleukin-5 receptor and the T-cell receptor. It is also required for G protein trafficking in sensory neurons [PMID: 21642972].

Mutations in the UNC119 gene cause immunodeficiency 13 (IMD13), a rare and heterogeneous syndrome defined by a reproducible reduction in the CD4 T-lymphocyte count [PMID: 22184408].
