[Name] UCHL1-003 [Transcript ID] ENST00000381760 [bp] 1578 [Protein] No protein [Translation ID] - [CCDS] - [UniProt] - [RefSeq] - [Flags] Transcript Support Level 2, when transcripts are supported by multiple ESTs or by an mRNA flagged as suspect.The Transcript Support Level (TSL) is a method to highlight the well-supported and poorly-supported transcript models for users. The method relies on the primary data that can support full-length transcript structure: mRNA and EST alignments supplied by UCSC and Ensembl.TSL:2 [Biotype] 
Alternatively spliced transcript that is believed to contain intronic sequence relative to other coding transcripts in a given locus.Retained intron
