TissueNA
Tissue SpecificityExpressed strongly in dorsal root ganglion, with only minor levels elsewhere in the body, smooth muscle cells, MTC cell line and C-cell carcinoma. Also expressed in vagus nerves within the head and neck region (PubMed:31647222). Isoform 1 is expressed preferentially in the central and peripheral nervous system. Isoform 2 is expressed preferentially in the dorsal root ganglion. {ECO:0000269|PubMed:15178348, ECO:0000269|PubMed:15302875, ECO:0000269|PubMed:31647222, ECO:0000269|PubMed:7720699, ECO:0000269|PubMed:9169448}.
