Background
Osteoactivin is an intracellular glycoprotein belongs to the NMB/pMEL-17 family; which is asscociated with cell endosomal/lysomal compartments. Human Osteoactivin is a 560 amino acid type I transmembrane protein; and one alternate splice form shows a 12 amino acid insert between amino acid 339-340. An additional 206 amino acid isoform shows a mutation at position 181 that results in a 26 amino acid substitution for the C-terminal 380 amino acids. Cells knowns to express Osteoactivin include fibroblast; osteoblasts; myeloid dendritic cell; melanocytes; plus fetal chondrocytes and stratum basale keratinocytes; macrophages/keratinocytes.
