Protease, Serine 3 (PRSS3)

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.

PRSS3were derived from genomic sequence to make the sequence consistent with the reference genome assembly. The genomic coordinates used for the transcript record were based on alignments.
