Descripción

General description

Prominin is a novel plasma membrane protein with an N-terminal extracellular domain, five transmembrane segments flanking two short cytoplasmic loops and two large glycosylated extracellular domains, and a cytoplasmic C-terminal domain. DNA sequences from Caenorhabditis elegans predict the existence of a protein with the same features, suggesting that prominin is conserved between vertebrates and invertebrates. Prominin is found not only in the neuroepithelium but also in various other epithelia of the mouse embryo. In the adult mouse, prominin has been detected in the brain ependymal layer, and in kidney tubules. In these epithelia, prominin is specific to the apical surface, where it is selectively associated with microvilli and microvilli-related structures. Remarkably, upon expression in CHO cells, prominin is preferentially localized to plasma membrane protrusions such as filopodia, lamellipodia, and microspikes. These observations imply that prominin contains information to be targeted to, and/or retained in, plasma membrane protrusions rather than the planar cell surface. Moreover, results show that the mechanisms underlying targeting of membrane proteins to microvilli of epithelial cells and to plasma membrane protrusions of non-epithelial cells are highly related. {Weigmann, A et al.1997}. Also see {http://www.ncbi.nlm.nih.gov/prow/guide/438375806_g.htm} for more information on CD133 and prominin expression.

Specificity

Recognizes mouse Prominin-1 (sometimes also referred to as CD133 and, in the case of the human orthologue, as AC133), a 115-120 kDa pentaspan transmembrane (5-TM) domain glycoprotein. Prominin-1 is expressed on primitive cells such as hematopoietic stem and progenitor cells, neural & endothelial stem cells, retina and retinoblastoma, as well as developing epithelium. To date, the function and ligand of Prominin-1 are unknown.

This antibody can be used to isolate murine stem cells from brain and bone marrow.

The 13A4 antibody does not cross react with rat, human, chicken, or Drosophila antigen. The original paper is located at: http://www.pnas.org/cgi/reprint/94/23/12425.pdf

Immunogen

Telencephali of ten 12-day-old NMRI mouse embryos (E12, ~1 mg protein), which consist mostly of neuroepithelium, were homogenized in 1 ml PBS, mixed with crushed nitrocellulose filter (1 cm2 in 0.5 ml PBS) as adjuvant, and injected i.p. into a LouXSD rat. {Weigmann et al, PNAS 1997}
