Gene Name	pleiotrophin
Database Link	Entrez Gene 5764 Human UniProt ID P21246
Background	Pleiotrophin (Osteoblast-Specific Factor-1, OSF-1) contains 136 amino acid residues. The sequence is very rich in cationic amino acids (24% of the residues); lysine cluster sequences are found in the N-terminal and Cterminal ends of the structure. The OSF-1 gene was shown by Northern blotting analysis to be expressed in mouse calvarial osteoblastenriched cells and in mouse brain tissues, but not in thymus, spleen, kidney, liver, lung, testis or heart. Pliotrophin has the ability to promote adhesion, migration, expansion, and differentiation of human osteoprogenitor cells. In addition to certain types of cancer, the embryonic growth and differentiation factor pleiotrophin is found also in adults in inflammatory diseases. In osteoarthritis, pleiotrophin is especially expressed in early stages, and its concentrations in the synovial fluid could serve as a marker for the progress of the disease. Pleitrophin might be involved in cartilage repair in osteoarthritis, in particular, in earlier stages. Total 152 AA. MW: 17.3 kDa. N-Terminal His-tag and thrombin cleavage site 16 AA (highlighted).
Synonyms	HBNF1, HBNF-1, NEGF1, HBBM, HBGF-8, HB-GAM, OSF1, OSF-1
