Protein: Protein unc-119 homolog A (Retinal protein 4) (rRG4) (Q62885)
Organism: Rattus norvegicus (Rat)
Function: 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 required for G-protein localization and trafficking in sensory neurons. Probably plays a role in trafficking proteins in photoreceptor cells. Plays important roles in mediating Src family kinase signals for the completion of cytokinesis via RAB11A.
Subcellular location: Cytoplasm, cytoskeleton, microtubule organizing center, centrosome {ECO:0000250|UniProtKB:Q13432}. Cytoplasm, cytoskeleton, spindle {ECO:0000250|UniProtKB:Q13432}. Cytoplasm, cytoskeleton, spindle pole {ECO:0000250|UniProtKB:Q13432}. Note=ocalizes to the centrosome in interphase cells and begins to translocate from the spindle pole to the spindle midzone after the onset of mitosis; it then localizes to the intercellular bridge in telophase cells and to the midbody in cytokinetic cells. {ECO:0000250|UniProtKB:Q13432}.
