Protein unc-119 homolog A (UNC119)

Involved in synaptic functions in photoreceptor cells, the signal transduction in immune cells as a Src family kinase activator, endosome recycling, the uptake of bacteria and endocytosis, protein trafficking in sensory neurons and as lipid- binding chaperone with specificity for a diverse subset of myristoylated proteins. Specifically binds the myristoyl moiety of a subset of N-terminally myristoylated proteins and is required for their localization.

Binds myristoylated GNAT1 and is needed for G-protein localization and trafficking in sensory neurons. Probably plays a role in trafficking proteins in photoreceptor cells.
