Purity: > 90% by SDS - PAGE Format: Liquid. In 20mM Tris-HCl buffer (pH 8.0) containing 0.2M NaCl, 50% glycerol, 5mM DTT, 2mM EDTA. Tubby-related protein 1, also known as TuLP1, is a member of the TuLP family of four proteins (TuB and TuLP1, -2, and -3), characterized structurally by the highly conserved C-terminal half of the protein. In the retina, TuLP1 is found exclusively in photoreceptor cells, localizing primarily in the inner segments and connecting cilium and to a lesser extent in the perinuclear cytoplasm and synaptic termini. Recombinant human TuLP1 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
