General description

Rab proteins are low molecular weight, ras-related GTPases that bind to a cell membrane’s cytoplasmic surface and function to regulate protein trafficking in both endocytic and secretory pathways. Rab escort protein (REP)-1 is a 653 amino acid protein belonging to the Rab GDI family of proteins. REP-1 binds to newly assembled unprenylated RAB proteins, escorts them to the Rab GGTases, and remains attached during and after the geranylgeranyl transfer reaction. REP proteins are composed of two conserved domains connected by a 150 amino acid insert. The multisheet domain I acts to assemble a Rab-binding platform. A globular, smaller, α-helical domain II, is thought to participate in membrane-protein interaction. Defects in the expression of REP-1 cause truncation or absence of the protein, and result in a disease called choroideremia (CHM), an X-linked blindness characterized by a progressive dystrophy of the retinal pigment epithelium, retina, and the choroid.

Specificity

This antibody recognizes REP-1.

Immunogen

Recombinant protein corresponding to human REP-1.

Application

Anti-REP-1 Antibody, clone 2F1 is an antibody against REP-1 for use in WB, IP, IC, IH.
Immunohistochemistry Analysis: A previous lot of MABN52 was successfully used in IH, as reported by an independent laboratory (MacDonald, I.M., et al. (2005). Invest Ophthalmol Vis Sci. 46:E-Abstract 540).

Quality

Evaluated by Western Blot in 293T cell lysate.

Western Blot Analysis: 0.5 µg/mL of this antibody detected REP-1 on 10 µg of 293T cell lysate.

Recent advances in recombinant adeno-associated virus (rAAV) gene therapy for choroideremia show gene replacement to be a promising approach. It is, however, well known that contact of vector solution with plastic materials in the surgical device may result in non-specific

Choroideremia results from the deficiency of Rab Escort Protein 1 (REP1), encoded by CHM, involved in the prenylation of Rab GTPases. Here, we investigate whether the transcription and expression of other genes involved in the prenylation of Rab proteins correlates
