Protein attributes

Sequence length	247 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Uncertain.

General annotation (Comments)

Catalytic activity	Preferential cleavage: Arg-|-Xaa, Lys-|-Xaa.
Subcellular location	Secreted Potential.
Tissue specificity	Overexpressed in metastasing in non small cell lung tumors, leading to an enhanced cell migration. Ref.2
Sequence similarities	Belongs to the peptidase S1 family. Tryptase subfamily. Contains 1 peptidase S1 domain.
Caution	Could be the product of a pseudogene. Although being similar to trypsinogen, it appears to be a transcribed pseudogene. ESTs support its transcription, but expression of its predicted protein has not been observed.
