The method relies on the primary data that can support full-length transcript structure: mRNA and EST alignments supplied by UCSC and Ensembl.TSL:1PRINCIPAL3 - APPRIS candidate principal isoform (earliest CCDS).APPRIS is a system to annotate alternatively spliced transcripts based on a range of computational methods.APPRIS P3 [Biotype] 
Transcript is thought to undergo nonsense mediated decay, a process which detects nonsense mutations and prevents the expression of truncated or erroneous proteins. Nonsense mediated decay
