It is shown to give good description of both the total proton structure function F2 and, as a prediction, the heavy quarks contribution F2c and F2b. The reasonable agreement for the longitudinal and diffractive structure functions is also found.4 pages, 2 figures; Talk presented at the 41th Rencontres de Moriond on QCD and High Energy Hadronic Interactions, La Thuile, Italy, March 18-25, 2006High Energy Physics - Phenomenologytext
