Anti-leucine-rich repeat, Ig-like and transmembrane domains 3 antibodies enable researchers to detect and measure the leucine-rich repeat, Ig-like and transmembrane domains 3 antigen in biological samples. This target is a reported synonym of the LRIT3 gene, which encodes leucine rich repeat, Ig-like and transmembrane domains 3. This protein is reported to play a role in the synapse formation and synaptic transmission between cone photoreceptor cells and retinal bipolar cells (By similarity). The human version of leucine-rich repeat, Ig-like and transmembrane domains 3 has a canonical amino acid length of 679 residues and a protein mass of 74.8 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell projections and ER of cells and notably expressed in the retina and testis.
