NIR2 Products

NIR2 belongs to a family of proteins that share homology with the Drosophila retinal degeneration B (rdgB) protein. Nir2, a human homolog of Drosophila melanogaster retinal degeneration B protein, is essential for cytokinesis. A specific Thr residue in the Nir2 PI-transfer domain provides a regulatory site for targeting to lipid droplets. This may affect intracellular lipid trafficking and distribution & explain the dominant effect of the RdgB-T59E mutant on retinal degeneration.
