Anti-UNC119 antibodies are used in the immunodetection of the protein unc-119 lipid binding chaperone. In humans, the canonical protein has a reported length of 240 amino acid residues and a mass of 27 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is found to be highly expressed in retina, in photoreceptor synapses and inner segments. A member of the PDE6D/unc-119 protein family, UNC119 is known to be 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. Synonyms for this target antigen include HRG4, IMD13, POC7, POC7A, protein unc-119 homolog A, POC7 centriolar protein homolog A, retinal protein 4, and CORD24. A number of UNC119 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
