特異性:This item recognises the human Secreated Frizzled-Related Protein 1 (SFRP1), a multi functional secreted protein belonging to the sFRP family. sFRPS function as modulators of Wnt signalling and have a role in the regulation of cell growth and differentiation in specific cell types. SFRP1 is widely expressed in human tissues (though absent from the lung, liver and peripheral blood leucocytes). Research demonstrates that SFRP1 has an anti-proliferative effect upon vascular cells, delaying the G1 phase and entry into S-phase in the cell cycle. It has also been demonstrated to that in kidney development, SFRP1 inhibits tubule formation and bud growth in metanephroi. Research has also indicated that SFRP1 acts a tumour suppressor protein.
