Function
- signaling adapter that couples activated growth factor receptors to signaling pathway in neurons
- involved in the signal transduction pathways of neurotrophin-activated Trk receptors in cortical neurons (putative)
- phosphorylated on Tyr by the Trk receptors
- interacts with Trk receptors (phospho-Tyr-dependent)
- once activated, binds to GRB2
Structure
- the PID domain mediates binding to the TrkA receptor
- contains 1 PID domain
- contains 1 SH2 domain
Expression
- expressed in brain
- expressed at high level in the hypothalamus
- expressed at low level in the caudate nucleus
