CC   -!- FUNCTION: BINDS TIGHTLY TO HYDROXYAPATITE. APPEARS TO FORM AN
CC       AN INTEGRAL PART OF THE MINERALIZED MATRIX. PROBABLY IMPORTANT
CC       TO CELL-MATRIX INTERACTION.
CC   -!- PTM: EXTENSIVELY PHOSPHORYLATED ON SERINE RESIDUES.
CC   -!- PTM: N- AND O-GLYCOSYLATED.
CC   -!- DISEASE: THIS PROTEIN PLAYS A PRINCIPAL ROLE IN URINARY STONE
CC       FORMATION AS THE STONE MATRIX.
CC   -!- ALTERNATIVE PRODUCTS: TWO FORMS OF OPN ARE PRODUCES BY ALTERNATIVE
CC       SPLICING OF THE SAME GENE. THEY DIFFER BY THE PRESENCE (OP1B) OR
CC       ABSENCE (OP1A) OF 14 AMINO ACIDS AT RESIDUE 58 OF THE MOLECULE.
