Receptor tyrosine kinase involved in the development and the maturation of the central and the peripheral nervous systems through regulation of neuron survival, proliferation, migration, differentiation, and synapse formation and plasticity. Receptor for BDNF/brain-derived neurotrophic factor and NTF4/neurotrophin-4. Alternatively can also bind NTF3/neurotrophin-3 which is less efficient in activating the receptor but regulates neuron survival through NTRK2. Upon ligand-binding, undergoes homodimerization, autophosphorylation and activation. Recruits, phosphorylates and/or activates several downstream effectors including SHC1, FRS2, SH2B1, SH2B2 and PLCG1 that regulate distinct overlapping signaling cascades. Through SHC1, FRS2, SH2B1, SH2B2 activates the GRB2-Ras-MAPK cascade that regulates for instance neuronal differentiation including neurite outgrowth. Through the same effectors controls the Ras-PI3 kinase-AKT1 signaling cascade that mainly regulates growth and survival. Through PLCG1 and the downstream protein kinase C-regulated pathways controls synaptic plasticity. Thereby, plays a role in learning and memory by regulating both short term synaptic function and long-term potentiation. PLCG1 also leads to NF-Kappa-B activation and the transcription of genes involved in cell survival. Hence, it is able to suppress anoikis, the apoptosis resulting from loss of cell-matrix interactions. May also play a role in neutrophin-dependent calcium signaling in glial cells.4 Publications

The neuronal activity and the influx of calcium positively regulate the kinase activity and the internalization of the receptor which are both important for active signaling. Regulated by NGFR that may control the internalization of the receptor. NGFR may also stimulate the activation by BDNF compared to NTF3 and NTF4. SH2D1A inhibits the autophosphorylation of the receptor, and alters the recruitment and activation of downstream effectors and signaling cascades. The formation of active receptors dimers able to fully transduce the ligand-mediated signal, may be negatively regulated by the formation of inactive heterodimers with the non-catalytic isoforms.1 Publication

Interacts with SH2B1 and SH2B2.

Interacts with NGFR; may regulate the ligand specificity of the receptor.

Interacts with SORCS2; this interaction is important for normal targeting to post-synaptic densities in response to high-frequency stimulation (By similarity).

Interacts (phosphorylated upon ligand-binding) with SH2D1A; regulates NTRK2.

Interacts with SQSTM1 and KIDINS220.

Interacts (phosphorylated upon ligand-binding) with FRS2; activates the MAPK signaling pathway.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
