Clone Host Grade Applications Monoclonal Rabbit Supernatant B IP FC

The trk proto-oncogene encodes a 140-kilodalton, membrane-spanning protein Trk that is expressed only in neural tissues. Nerve growth factor (NGF) stimulates phosphorylation of Trk in neural cell lines and in embryonic dorsal root ganglia. Affinity cross-linking and equilibrium binding experiments indicate that Trk binds NGF specifically in cultured cells with a dissociation constant of 10(-9) molar. The identification of Trk as an NGF receptor indicates that this protein participates in the primary signal transduction mechanism of NGF (1). Nerve growth factor and its high-affinity receptor Trk are thought to be involved in the progression of various cancers (2). NGF interacts with two different low-affinity receptors that can be distinguished by affinity crosslinking. Reconstitution experiments by membrane fusion and transient transfection into heterologous cells indicate that high-affinity NGF binding requires coexpression and binding to both the low-affinity NGF receptor and Trk. These studies reveal a new growth factor receptor-mediated mechanism of cellular differentiation involving Trk and the low-affinity NGF receptor (3).
