This gene encodes a member of the neurotrophic tyrosine kinase receptor (NTKR) family. This kinase is a membrane-bound receptor that, upon neurotrophin binding, phosphorylates itself and members of the MAPK pathway. The presence of this kinase leads to cell differentiation and may play a role in specifying sensory neuron subtypes. Mutations in this gene have been associated with congenital insensitivity to pain, anhidrosis, self-mutilating behavior, cognitive disability and cancer. Alternate transcriptional splice variants of this gene have been found, but only three have been characterized to date. [provided by RefSeq, Jul 2008] CIViC Summary for NTRK1 Gene
Forensic Context
A study in human and rat corpus cavernosum tissue demonstrated that the NTRK1 was mentioned as an example of evolutionary divergence in sensory neurons within the introductory or discussion sections of the literature [Yin et al. DOI:10.1016/j.celrep.2024.114760].
