Activity summary

GPNMB also known as osteoactivin is a type I transmembrane glycoprotein with a molecular mass of approximately 115 kDa. This protein is highly expressed in various tissues including the bone skin and brain. It also shows notable presence in certain immune cells such as dendritic cells and macrophages. GPNMB localizes mainly on the cell membrane and within lysosomal compartments indicating its involvement in cellular and signaling processes.

Biological function summary

GPNMB plays versatile roles in promoting cell growth differentiation and repair. It is involved in processes like tissue regeneration possibly due to its role in cell adhesion and migration. The protein also partakes in osteoclast differentiation and bone resorption therefore linking to skeletal homeostasis. GPNMB forms part of a broader protein complex at the cellular junctions interacting with integrins to mediate its functions.

Pathways

GPNMB features prominently in osteoclastogenesis and melanoma metastasis pathways. It cooperates with RANKL an important protein in bone metabolism by influencing osteoclast differentiation and activation. In the context of melanoma GPNMB's action in pathways may enhance tumor proliferation and invasion possibly interacting with signaling molecules like AKT or ERK although the specifics remain actively researched.

Associated diseases and disorders

GPNMB has significant links to both osteoarthritis and certain types of cancer particularly breast cancer and melanoma. In osteoarthritis GPNMB expression often increases reflecting involvement in cartilage degradation processes. Its overexpression correlates with tumor progression in melanoma potentially driven by its interaction with integrin β1 which assists in cellular adhesion and migration within the tumor microenvironment.
