This CCDS ID represents the protein described in PMID: 16792503 and is supported by the mRNA BC049168.1. It should be noted that this transcript is predicted to undergo nonsense-mediated mRNA decay (NMD). However, the protein is represented because it was detected endogenously in PMID: 16792503. It is likely that the majority of transcripts representing this variant will undergo NMD, while some low level of NMD escape may allow for the expression of this protein.
