| Background: |
Although this locus appears to encode a protein similar to trypsinogen, the locus is thought to be a transcribed pseudogene. ESTs support its transcription, but expression of its predicted protein has not been observed. Its predicted protein sequence differs significantly from the known functional trypsinogens, including a different amino acid at the conserved residue 122 which is important for autolysis. This pseudogene and several other trypsinogen genes are localized to the T cell receptor beta locus on chromosome 7. [provided by RefSeq, Jul 2008], |
