Dendritic cell-specific transmembrane protein (Dcstamp)

Probable cell surface receptor which plays several roles in cellular fusion, cell differentiation, bone and immune homeostasis. Cooperates with OCSTAMP in modulating cell-cell fusion in both osteoclasts and foreign body giant cells (FBGCs).

Participates in osteoclast bone resorption. Involved in inducing the expression of tartrate-resistant acid phosphatase in osteoclast precursors.
