WB (Western Blot)

(Western blot analysis of Phospho-TrkA (Tyr496) in lysates of jurkat?, using Phospho-TrkA (Tyr496) Antibody.)

IHC (Immunohistochemistry)

(At 1/100 staining human kidney tissue sections by IHC-P. The tissue was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The tissue was then blocked and incubated with the antibody for 1.5 hours at 22 degree C. An HRP conjugated goat anti-rabbit antibody was used as the secondary)

Description: Receptor tyrosine kinase involved in the development and the maturation of the central and peripheral nervous systems through regulation of proliferation, differentiation and survival of sympathetic and nervous neurons. High affinity receptor for NGF which is its primary ligand (PubMed:1850821, PubMed:1849459, PubMed:1281417, PubMed:8325889, PubMed:15488758, PubMed:17196528, PubMed:27445338). Can also bind and be activated by NTF3/neurotrophin-3. However, NTF3 only supports axonal extension through NTRK1 but has no effect on neuron survival (By similarity). Upon dimeric NGF ligand-binding, undergoes homodimerization, autophosphorylation and activation (PubMed:1281417). Recruits, phosphorylates and/or activates several downstream effectors including SHC1, FRS2, SH2B1, SH2B2 and PLCG1 that regulate distinct overlapping signaling cascades driving cell survival and differentiation. Through SHC1 and FRS2 activates a GRB2-Ras-MAPK cascade that regulates cell differentiation and survival. Through PLCG1 controls NF-Kappa-B activation and the transcription of genes involved in cell survival. Through SHC1 and SH2B1 controls a Ras-PI3 kinase-AKT1 signaling cascade that is also regulating survival. In absence of ligand and activation, may promote cell death, making the survival of neurons dependent on trophic factors.

Post Translational Modifications: Ligand-mediated autophosphorylation (PubMed:2927393, PubMed:1281417, PubMed:15488758, PubMed:7510697, PubMed:8155326, PubMed:8325889, PubMed:27676246, PubMed:28177573). Interaction with SQSTM1 is phosphotyrosine-dependent. Autophosphorylation at Tyr-496 mediates interaction and phosphorylation of SHC1 (PubMed:15488758, PubMed:7510697, PubMed:8155326, PubMed:8325889). N-glycosylated (PubMed:2927393). Isoform TrkA-I and isoform TrkA-II are N-glycosylated. Ubiquitinated (PubMed:27445338). Undergoes polyubiquitination upon activation; regulated by NGFR (PubMed:27445338). Ubiquitination by NEDD4L leads to degradation (PubMed:27445338). Ubiquitination regulates the internalization of the receptor (By similarity).

Subunit Structure: Exists in a dynamic equilibrium between monomeric (low affinity) and dimeric (high affinity) structures. Homodimerization is induced by binding of a NGF dimer (PubMed:1281417, PubMed:10490030, PubMed:17196528). Interacts with SQSTM1; bridges NTRK1 to NGFR (PubMed:11244088). Forms a ternary complex with NGFR and KIDINS220; this complex is affected by the expression levels of KIDINS220 and an increase in KIDINS220 expression leads to a decreased association of NGFR and NTRK1 (By similarity). Interacts with SH2D1A; regulates NTRK1 (By similarity). Interacts (phosphorylated upon activation by NGF) with SHC1; mediates SHC1 phosphorylation and activation (PubMed:8155326, PubMed:15488758). Interacts (phosphorylated upon activation by NGF) with PLCG1; mediates PLCG1 phosphorylation and activation (PubMed:7510697, PubMed:15488758). Interacts (phosphorylated) with SH2B1 and SH2B2 (By similarity). Interacts with GRB2 (PubMed:15488758). Interacts with PIK3R1 (PubMed:15488758). Interacts with FRS2 (PubMed:15488758). Interacts with SORT1; may regulate NTRK1 anterograde axonal transport (PubMed:21102451). Interacts with RAB7A (By similarity). Found in a complex, at least composed of KIDINS220, MAGI2, NTRK1 and RAPGEF2; the complex is mainly formed at late endosomes in a nerve growth factor (NGF)-dependent manner (By similarity). Interacts with RAPGEF2; the interaction is strengthened after NGF stimulation (By similarity). Interacts with PTPRS (By similarity). Interacts with USP36; USP36 does not deubiquitinate NTRK1 (PubMed:27445338).

Similarity: The transmembrane domain mediates interaction with KIDINS220. The extracellular domain mediates interaction with NGFR. Belongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily.
