Background
caution:Although related to peptidase S1 family, lacks the conserved active Ser residue in position 310 which is replaced by a Thr, suggesting that it has no protease activity.,miscellaneous:DNA hypomethylation is accompanied by the expression of the gene in the testis.,similarity:Belongs to the peptidase S1 family.,similarity:Contains 1 peptidase S1 domain.,tissue specificity:Testis specific. Differentially expressed in some breast cancer tissues.,
