Identification of mammalian GFRalpha-2 splice isoforms.
Neurturin (NTN) belongs to a structurally related family of bioactive molecules which include glial cell-line derived neutrotrophic factor (GDNF) and perserphin (PSP). NTN exerts its effects through a multicomponent receptor system which include a receptor (GFRalpha-2) and the proto-oncogene c-RET. We report here the identification of three splice isoforms of the GFRalpha-2 receptors (GFRalpha-2a, GFRalpha-2b and GFRalpha-2c) by reverse transcription-PCR (RT-PCR). GFRalpha-2b is a novel splice variant. All three isoforms were found to be expressed in various adult murine tissues as well as in the brain of the newborn human. The identity of these isoforms were further confirmed by the isolation of the gene and the characterisation of the splice junctions.
