MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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 cell differentiation. Mutations in this gene have been associated with obesity and mood disorders. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]
PHENOTYPE: Different lines of homozygous mice show varied abnormalities including innervation and neural defects, rod defects, impaired ovarian folliculogenesis, and reduced postnatal survival. Homozygotes for a point mutation are normal, but are subject to pharmacological control of signalling. [provided by MGI curators]
