Target Species
Human
Target Name
GPNMB
Target Full Name
Transmembrane glycoprotein NMB
Target Function
Could be a melanogenic enzyme.
Target Involvement
Glioblastoma multiforme patients that exhibit increased mRNA and protein levels (>3-fold over normal brain) in biopsy samples have a significantly higher risk of death (PubMed:16609006). In the context of cancer immunotherapy, including that of melanoma, has been proposed to be used as a cell surface protein antigen targeted by antibodies coupled to cytotoxic drugs (PubMed:16489096).
Target Subcellular Location
Cell membrane; Single-pass type I membrane protein. Melanosome membrane; Single-pass type I membrane protein. Early endosome membrane; Single-pass type I membrane protein.
Target Protein Families
PMEL/NMB family
Target Tissue Specificity
Widely expressed, but very low expression, if any, in the brain. Expressed in the epidermis with higher levels in melanocytes compared with keratinocytes and Langerhans cells (at protein level). Expressed in peripheral blood, but not bone marrow mononucle
Target Research Area
Immunology
Target Synonyms
Glycoprotein (transmembrane) nmb; Glycoprotein nmb; Glycoprotein nmb like protein; Gpnmb; GPNMB_HUMAN; HGFIN; NMB; Osteoactivin; Transmembrane glycoprotein; Transmembrane glycoprotein HGFIN; Transmembrane glycoprotein NMB
Target Background
The protein encoded by this gene is a type I transmembrane glycoprotein which shows homology to the pMEL17 precursor, a melanocyte-specific protein. GPNMB shows expression in the lowly metastatic human melanoma cell lines and xenografts but does not show expression in the highly metastatic cell lines. GPNMB may be involved in growth delay and reduction of metastatic potential. Two transcript variants encoding different isoforms have been found for this gene.
