Fgr: Proteins and Enzymes

Fgr is the cellular homolog of the oncogenic protein encoded by the Gardner-Rasheed feline sarcoma virus. A member of the Src family of nonreceptor tyrosine kinases, Fgr is predominantly expressed in neutrophils, macrophages, monocytes, and natural killer cells. Mice lacking Fgr fail to recruit eosinophils to the lung during allergic airway inflammation.
