PTX1 is a gene identified by subtractive hybridization on the basis that it is expressed in normal prostate and not in prostate carcinoma. It is unrelated to the pituitary homeobox protein (Ptx1 or Pitx1), which regulates pituitary hormone gene expression, and its function is currently unknown. Recently, it was found to be a homolog of the yeast Erv41p, an(More)
A cDNA, designated PTX1, has been isolated by subtractive hybridization on the basis that it is expressed in normal prostate but not in prostate carcinoma. The full-length cDNA was subsequently established by 5' and 3' RACE. Nucleotide sequence analysis of the 5'- and 3'-RACE clones yielded a composite cDNA of 1327 bp, which predicted a protein of 377 amino(More)
PTX1 is a gene identified by subtractive hybridization on the basis that it is expressed in normal prostate and not in prostate carcinoma. It encodes a nuclear protein that is downregulated in prostate carcinoma. Expression constructs containing PTX1 cDNA in both sense and antisense orientations were transfected into prostate tumor cell line, PC-3 cells.(More)
