TissueNA
Tissue SpecificityMainly expressed in brain although also detected in other tissues like heart and skeletal muscle. Isoform 1 and isoform 2 are specifically expressed in neuronal tissues. Isoform 3 and isoform 4 are expressed in non-neuronal tissues. Isoform 5 and isoform 6 are truncated forms expressed in non-neuronal tissues. {ECO:0000269|PubMed:11003644, ECO:0000269|PubMed:12213192}.
