The androgen-dependent rat prostate protein, probasin, is a heparin-binding protein that co-purifies with
Abstract:
Rat prostate extracts contain an abundant 20-22 kilodalton heparin-binding protein with near identical chromatographic properties, but only 0.2-1% of the mitogenic activity, of bovine brain heparin-binding growth factor-1 (acidic fibroblast growth factor). Amino terminal amino acid sequence (met-met-thr-asp-lys-asn-leu-lys-lys-lys-ile-glu-gly-asn-trp-arg-thr-val -tyr- leu-ala-ala-ser-?-val-glu-lys-ile-asn-glu-gly-ser-pro) and immunochemical analysis revealed that the protein is identical to the androgen-dependent protein "probasin".
