Gene Gene information from NCBI Gene database.
Entrez ID 4915
Gene name Neurotrophic receptor tyrosine kinase 2
Gene symbol NTRK2
Synonyms (NCBI Gene)
DEE58EIEE58GP145-TrkBOBHDTRKBtrk-B
Chromosome 9
Chromosome location 9q21.33
Summary This gene encodes a member of the neurotrophic tyrosine receptor kinase (NTRK) family. This kinase is a membrane-bound receptor that, upon neurotrophin binding, phosphorylates itself and members of the MAPK pathway. Signalling through this kinase leads to
