Background: Prominin 2

Prominin 2 is a large-scale effort, termed the Secreted Protein Discovery Initiative (SPDI), was undertaken to identify novel secreted and transmembrane proteins. Several criteria were applied to identify and characterize these new and novel genes. First, a biological signal sequence trap in yeast cells was utilized to identify cDNA clones encoding putative secreted proteins, second strategy utilized various algorithms that recognize features such as the hydrophobic properties of signal sequences to identify putative proteins encoded by expressed sequence tags (ESTs) from human cDNA libraries and finally, ESTs for protein sequence similarity to a set of known receptors and their ligands with the BLAST algorithm. Based on these criteria isolation of full length cDNA clones for each of these genes resulted in identification of more than 1000 novel proteins. One of these new genes is Prominin2. Prominin 2 is a 112 kDa glycoporotein structurally related to Prominin 1 (CD133) although amino acid similarity is not more than 30% but their genomic organization is strikingly similar (1). Like Prominin1, the prominin 2 exhibit similar membrane topology with 5 trans-membrane domains and two large glycosylated extracellular domains. Similar to Prominin1 localization, the Prominin 2 is also associated with membrane protrusions of the epithelial cells from adult kidney, and all along the digestive track and other epithelial tissues. One striking difference between Prominin1 and Prominin 2 expression lies in its conspicuous absence in eye tissue (2). Prominin 2, along with other genes (AP1M2, MAL2, PRSS8 and FLJ20171) expression is differentially expressed in chromophobe renal cell carcinoma compared to benign oncocytoma consistently and this marker can be used to differentiate RCC form benign oncocytoma (3). Prominin 2 is an androgen-responsive genes proapoptotic membrane protein that is expressed in human prostate and human prostate cancer cell lines with highest levels in less aggressive LNCaP cell and low expression in highly aggressive PC3 and DU145 cells suggesting a role of Prominin 2 in down-regulation of aggressiveness of prostate cancer cells (4).
